### TCS NQT Coding Question 2020 – Day 1 – Slot 1

There is a JAR full of candies for sale at a mall counter. JAR has the capacity N, that is JAR can contain maximum N candies when JAR is full. At any point of time. JAR can have M number of Candies where M<=N. Candies are served to the customers. JAR is never remain empty as when last k candies are left. JAR if refilled with new candies in such a way that JAR get full.
Write a code to implement above scenario. Display JAR at counter with available number of candies. Input should be the number of candies one customer can order at point of time. Update the JAR after each purchase and display JAR at Counter.

Output should give number of Candies sold and updated number of Candies in JAR.

If Input is more than candies in JAR, return: “INVALID INPUT”

Given,

N=10, where N is NUMBER OF CANDIES AVAILABLE

K =< 5, where k is number of minimum candies that must be inside JAR ever.

Example 1:(N = 10, k =< 5)

• Input Value
• 3
• Output Value
• NUMBER OF CANDIES SOLD : 3
• NUMBER OF CANDIES AVAILABLE : 7

Example : (N=10, k<=5)

• Input Value
• 0
• Output Value
• INVALID INPUT
• NUMBER OF CANDIES LEFT : 10
```#include<stdio.h>
int main()
{
int n=10, k=5;
int num;
scanf("%d",&num);
if(num>=1 && num<=5)
{
printf("NUMBER OF CANDIES SOLD : %d\n",num);
printf("NUMBER OF CANDIES LEFT : %d",n-num);
}
else
{
printf("INVALID INPUT\n");
printf("NUMBER OF CANDIES LEFT : %d",n);
}
return 0;
}

```
```#include <iostream.h>

int n = 10, k = 5;
int num;
Scanner sc = new Scanner(System.in);
num = sc.nextInt();
if(num >= 1 && num <= 5) {
System.out.println("NUMBER OF CANDIES SOLD : " + num);
System.out.print("NUMBER OF CANDIES LEFT : " + (n - num));
} else {
System.out.println("INVALID INPUT");
System.out.print("NUMBER OF CANDIES LEFT : " + n);
}
}
}
```
```total_candies = 10
no_of_candies = int(input())
if no_of_candies in range(1, 6):
print('No. of Candies Sold:',no_of_candies)
print('No. of Candies Left:',total_candies-no_of_candies)
else:

### TCS NQT Coding Question 2020 – Day 1 – Slot 1

Selection of MPCS exams include a fitness test which is conducted on ground. There will be a batch of 3 trainees, appearing for running test in track for 3 rounds. You need to record their oxygen level after every round. After trainee are finished with all rounds, calculate for each trainee his average oxygen level over the 3 rounds and select one with highest oxygen level as the most fit trainee. If more than one trainee attains the same highest average level, they all need to be selected.

Display the most fit trainee (or trainees) and the highest average oxygen level.

Note:

• The oxygen value entered should not be accepted if it is not in the range between 1 and 100.
• If the calculated maximum average oxygen value of trainees is below 70 then declare the trainees as unfit with meaningful message as “All trainees are unfit.
• Average Oxygen Values should be rounded.

Example 1:

• INPUT VALUES

95

Problem Statement

A washing machine works on the principle of Fuzzy System, the weight of clothes put inside it for washing is uncertain But based on weight measured by sensors, it decides time and water level which can be changed by menus given on the machine control area.

For low level water, the time estimate is 25 minutes, where approximately weight is between 2000 grams or any nonzero positive number below that.

For medium level water, the time estimate is 35 minutes, where approximately weight is between 2001 grams and 4000 grams.

For high level water, the time estimate is 45 minutes, where approximately weight is above 4000 grams.

Assume the capacity of machine is maximum 7000 grams

Where approximately weight is zero, time estimate is 0 minutes.

Write a function which takes a numeric weight in the range [0,7000] as input and produces estimated time as output is: “OVERLOADED”, and for all other inputs, the output statement is

“INVALID INPUT”.

Input should be in the form of integer value –

Output must have the following format –

Time Estimated: Minutes

Example:

• Input value

2000

• Output value

Time Estimated: 25 minutes

Solution

```#include<stdio.h>
void calculateTime(int n)
{
if(n==0)
printf("Time Estimated : 0 Minutes");
else if(n>0 && n<=2000)
printf("Time Estimated : 25 Minutes");
else if(n>2000 && n<=4000)
printf("Time Estimated : 35 Minutes");
else if(n>4000 && n<=7000)
printf("Time Estimated : 45 Minutes");
else
printf("INVALID INPUT");
}
int main()
{
int machineWeight;
scanf("%d",&machineWeight);
calculateTime(machineWeight);
return 0;
}```
```n = int(input())
if n==0:
print("Time Estimated : 0 Minutes")
elif n in range(1,2001):
print("Time Estimated : 25 Minutes")
elif n in range(2001,4001):
print("Time Estimated : 35 Minutes")
elif n in range(4001,7001):
print("Time Estimated : 45 Minutes")
else:
print("INVALID INPUT")```

### TCS Coding Question Day 1 Slot 2 – Question 2

Problem Statement

The Caesar cipher is a type of substitution cipher in which each alphabet in the plaintext or messages is shifted by a number of places down the alphabet.
For example,with a shift of 1, P would be replaced by Q, Q would become R, and so on.
To pass an encrypted message from one person to another, it is first necessary that both parties have the ‘Key’ for the cipher, so that the sender may encrypt and the receiver may decrypt it.
Key is the number of OFFSET to shift the cipher alphabet. Key can have basic shifts from 1 to 25 positions as there are 26 total alphabets.
As we are designing custom Caesar Cipher, in addition to alphabets, we are considering numeric digits from 0 to 9. Digits can also be shifted by key places.
For Example, if a given plain text contains any digit with values 5 and keyy =2, then 5 will be replaced by 7, “-”(minus sign) will remain as it is. Key value less than 0 should result into “INVALID INPUT”

Example 1:
Enter your PlainText: All the best
Enter the Key: 1

The encrypted Text is: Bmm uif Cftu

Write a function CustomCaesarCipher(int key, String message) which will accept plaintext and key as input parameters and returns its cipher text as output.

`#include <stdio.h>int main(){    char str;    int key, i=0, left;    printf("Enter your plain text : ");    scanf("%[^\n]s",str);    printf("Enter the key : ");    scanf("%d",&key);    if(key==0)    {        printf("INVALID INPUT");    }    else    {        while(str[i]!='\0')        {            //printf("%d\n", str[i]);            if(str[i]>=48 && str[i]<=57)            {                if(str[i]+key<=57)                {                    str[i] = str[i] + key;                }                else                {                    left = (str[i] + key) - 57;                    str[i] = 47 + left;                }               }            else if(str[i]>=65 && str[i]<=90)            {                if(str[i]+key<=90)                {                    str[i] = str[i] + key;                }                else                {                    left = (str[i] + key) - 90;                    str[i] = 64 + left;                }              }            else if(str[i]>=97 && str[i]<=122)            {                if(str[i]+key<=122)                {                    str[i] = str[i] + key;                }                else                {                    left = (str[i] + key) - 122;                    str[i] = 96 + left;                }             }            i++;        }        printf("The encrypted text is : %s",str);   }   return 0;}`

Problem Statement

A City Bus is a Ring Route Bus which runs in circular fashion.That is, Bus once starts at the Source Bus Stop, halts at each Bus Stop in its Route and at the end it reaches the Source Bus Stop again.
If there are n  number of Stops and if the bus starts at Bus Stop 1, then after nth Bus Stop, the next stop in the Route will be Bus Stop number 1 always.
If there are n stops, there will be n paths.One path connects two stops. Distances (in meters) for all paths in Ring Route is given in array Path[] as given below:
Path = [800, 600, 750, 900, 1400, 1200, 1100, 1500]
Fare is determined based on the distance covered from source to destination stop as  Distance between Input Source and Destination Stops can be measured by looking at values in array Path[] and fare can be calculated as per following criteria:

• If d =1000 metres, then fare=5 INR
• (When calculating fare for others, the calculated fare containing any fraction value should be ceiled. For example, for distance 900n when fare initially calculated is 4.5 which must be ceiled to 5)

Path is circular in function. Value at each index indicates distance till current stop from the previous one. And each index position can be mapped with values at same index in BusStops [] array, which is a string array holding abbreviation of names for all stops as-
“THANERAILWAYSTN” = ”TH”, “GAONDEVI” = “GA”, “ICEFACTROY” = “IC”, “HARINIWASCIRCLE” = “HA”, “TEENHATHNAKA” = “TE”, “LUISWADI” = “LU”, “NITINCOMPANYJUNCTION” = “NI”, “CADBURRYJUNCTION” = “CA”

Given, n=8, where n is number of total BusStops.
BusStops = [ “TH”, ”GA”, ”IC”, ”HA”, ”TE”, ”LU”, ”NI”,”CA” ]

Write a code with function getFare(String Source, String Destination) which take Input as source and destination stops(in the format containing first two characters of the Name of the Bus Stop) and calculate and return travel fare.

Problem Statement

There are total n number of Monkeys sitting on the branches of a huge Tree. As travelers offer Bananas and Peanuts, the Monkeys jump down the Tree. If every Monkey can eat k Bananas and j Peanuts. If total m number of Bananas and p number of Peanuts are offered by travelers, calculate how many Monkeys remain on the Tree after some of them jumped down to eat.
At a time one Monkeys gets down and finishes eating and go to the other side of the road. The Monkey who climbed down does not climb up again after eating until the other Monkeys finish eating.
Monkey can either eat k Bananas or j Peanuts. If for last Monkey there are less than k Bananas left on the ground or less than j Peanuts left on the ground, only that Monkey can eat Bananas(<k) along with the Peanuts(<j).
Write code to take inputs as n, m, p, k, j and return  the number of Monkeys left on the Tree.
Where, n= Total no of Monkeys
k= Number of eatable Bananas by Single Monkey (Monkey that jumped down last may get less than k Bananas)
j = Number of eatable Peanuts by single Monkey(Monkey that jumped down last may get less than j Peanuts)
m = Total number of Bananas
p  = Total number of Peanuts
Remember that the Monkeys always eat Bananas and Peanuts, so there is no possibility of k and j having a value zero

#### Checking if a given year is leap year or not

Explanation:

To check whether a year is leap or not

Step 1:

• We first divide the year by 4.
• If it is not divisible by 4 then it is not a leap year.
• If it is divisible by 4 leaving remainder 0

Step 2:

• We divide the year by 100
• If it is not divisible by 100 then it is a leap year.
• If it is divisible by 100 leaving remainder 0

Step 3:

• We divide the year by 400
• If it is not divisible by 400 then it is a leap year.
• If it is divisible by 400 leaving remainder 0

Then it is a leap year

`#include<stdio.h>int leapprog(int year){//checking divisibility by 4    if(year%4 == 0)    {//checking divisibility by 100        if( year%100 == 0)        {//checking divisibility by 400            if ( year%400 == 0)                printf("%d, the year entered happens to be a leap year", year);            else                printf("%d is surely not a leap year", year);        }        else            printf("%d, the year entered happens to be a leap year", year );    }    else        printf("%d is surely not a leap year", year);        return 0;}int main(){    int input_year, val;    printf("Enter the year that you want to check"); //enter the year to check    scanf("%d",&input_year);    val = leapprog(input_year);    return 0;}`
`//C++ Program//Leap year or not#include<stdio.h>using namespace std;//main programint main(){	//initialising variables	int year;	cout<<"Enter year to check: ";	//user input	cin>>year;	//checking for leap year	if( ((year % 4 == 0)&&(year % 100 != 0)) || (year % 400==0) )	{		//input is a leap year		cout<<year<<" is a leap year";	}	else	{		//input is not a leap year		cout<<year<< " is not a leap year";	}	return 0;}`

#### Output:

`Enter year to check: 2019`

2019 is not a leap year

#### Prime Numbers with a Twist

Ques. Write a code to check whether no is prime or not. Condition use function check() to find whether entered no is positive or negative ,if negative then enter the no, And if yes pas no as a parameter to prime() and check whether no is prime or not?

• Whether the number is positive or not, if it is negative then print the message “please enter the positive number”
• It is positive then call the function prime and check whether the take positive number is prime or not.

`#include<stdio.h>void prime(int n){int c=0;    for(int i=2;i<n;i++)    {        if(n%i==0)        c = c+1;    }    if(c>=1)        printf("%d is not a prime number",n);    else        printf("%d is a prime number",n);}void main(){int n;printf("Enter no : "); //enter the numberscanf("%d",&n);if(n<0)    {    printf("Please enter a positive integer");    }else    prime(n);}`

#### Number Series with a Twist – 1

Find the 15th term of the series?

0,0,7,6,14,12,21,18, 28

Explanation : In this series the odd term is increment of 7 {0, 7, 14, 21, 28, 35 – – – – – – }

And even term is a increment of 6 {0, 6, 12, 18, 24, 30 – – – – – – }

`#include <stdio.h>int main(){   int i, n, a=0, b=0;   printf("enter number : ");   scanf("%d",&n);   for(i=1;i<=n;i++)   {      if(i%2!=0)      {           a = a + 7;      }       else      {               b = b + 6;      }   }      if(n%2!=0)      {           printf("%d term of series is %d\t",n,a-7);      }      else      {               printf("%d term of series is %d\t",n,b-6);      }return 0; }`

#### Number Series with a Twist 2

Consider the following series: 1, 1, 2, 3, 4, 9, 8, 27, 16, 81, 32, 243, 64, 729, 128, 2187 …

This series is a mixture of 2 series – all the odd terms in this series form a geometric series and all the even terms form yet another geometric series. Write a program to find the Nth term in the series.

The value N in a positive integer that should be read from STDIN. The Nth term that is calculated by the program should be written to STDOUT. Other than value of n th term,no other character / string or message should be written to STDOUT. For example , if N=16, the 16th term in the series is 2187, so only value 2187 should be printed to STDOUT.

You can assume that N will not exceed 30.

`#include<stdio.h>int main(){   int i, n, a=1, b=1;   printf("enter number : ");   scanf("%d",&n);   for(i=1;i<=n;i++)   {       if(i%2!=0)       {           a = a * 2;       }       else       {                b = b * 3;       }   }    if(n%2!=0)       {           printf("\n%d term of series is %d\t",n,a/2);       }       else       {               printf("\n%d term of series is %d\t",n,b/3);       }return 0;}`
`//C++ Program#include#includeusing namespace std;int main(){  //initialising variables  int n,r,term;  cout<<"Enter the position: ";  //user input  cin>>n;  //logic to find nth element of the series  if(n==1||n==2)  {    cout<<1;    return 0;   }  else if(n%2==0)  {    n=n/2-1;    r=3;   }  else  {    n=n/2;    r=2;  }  //logic ends here  //printing output  cout<<(int)(pow(r,n));  return 0;}`

#### Output:

`Enter the position: 17256`

#### Code :

`//Java program to find nth element of the seriesimport java.util.Scanner;class Main{	public static void main(String[] args)	{		Scanner sc = new Scanner(System.in);		//input value of n		System.out.print("Enter the value of n : ");						int n = sc.nextInt();		int a = 1, b = 1;		//statement for even value of n		if(n % 2 == 0)		{			for(int i = 1 ; i <= (n-2) ; i = i+2)			{				a = a * 2;				b = b * 3;			}			System.out.print(n+" element of the series is = "+b);		}		//statement for odd value of n		else		{			for(int i = 1 ; i < (n-2) ; i = i+2)			{				a = a * 2;				b = b * 3;			}			a = a * 2;			System.out.print(n+" element of the series is = "+a);		}	}}`

#### Output :

`Enter the value of n : 1414 element of the series is = 729`

#### Output

`enter number : 1717 term of series is 256`

#### Number Series with a Twist 3

Consider the below series :

0, 0, 2, 1, 4, 2, 6, 3, 8, 4, 10, 5, 12, 6, 14, 7, 16, 8

This series is a mixture of 2 series all the odd terms in this series form even numbers in ascending order and every even terms is derived from the previous  term using the formula (x/2)

Write a program to find the nth term in this series.

The value n in a positive integer that should be read from STDIN the nth term that is calculated by the program should be written to STDOUT. Other than the value of the nth term no other characters /strings or message should be written to STDOUT.

For example if n=10,the 10 th term in the series is to be derived from the 9th term in the series. The 9th term is 8 so the 10th term is (8/2)=4. Only the value 4 should be printed to STDOUT.

You can assume that the n will not exceed 20,000.

```#include<stdio.h>

int main()
{
int i, n, a=0, b=0;
printf("enter number : ");
scanf("%d",&n);

for(i=1;i<=n;i++)
{
if(i%2!=0)
{
if(i>1)
a = a + 2;
}
else
{
b = a/2;
}
}

if(n%2!=0)
{
printf("%d",a);
}
else
{
printf("%d",b);
}

return 0;
}```
```#include<iostream>
using namespace std;

for(i=1;i<=n;i++)
{

{
if(i>1)
a = a + 2;
}
else
{
b = a/2;
}
}

if(n%2!=0)
{
cout << a;
}
else
{
cout << b;
}

return 0;
}```
`//Java program to find nth element of the seriesimport java.util.Scanner;class Main{  public static void main(String[] args)  {    Scanner sc = new Scanner(System.in);    int n = sc.nextInt();    int a = 0, b = 0;    if(n % 2 == 0)    {      for(int i = 1 ; i <= (n-2) ; i = i+2)      {        a = a + 2;        b = a / 2;      }      System.out.print(b);     }     else     {       for(int i = 1 ; i < (n-2) ; i = i+2)       {         a = a + 2;         b = a / 2;       }       a = a + 2;       System.out.print(a);     }   }}`

#### String with a Twist

1. The program will recieve 3 English words inputs from STDIN

1. These three words will be read one at a time, in three separate line
2. The first word should be changed like all vowels should be replaced by %
3. The second word should be changed like all consonants should be replaced by #
4. The third word should be changed like all char should be converted to upper case
5. Then concatenate the three words and print them

Other than these concatenated word, no other characters/string should or message should be written to STDOUT

For example if you print how are you then output should be h%wa#eYOU.

You can assume that input of each word will not exceed more than 5 chars

```#include <stdio.h>

#### Addition of two numbers a Twist

1. Using a method, pass two variables and find the sum of two numbers.

Test case:

Number 1 – 20

Number 2 – 20.38

Sum = 40.38

There were a total of 4 test cases. Once you compile 3 of them will be shown to you and 1 will be a hidden one. You have to display error message if numbers are not numeric.

`#include<stdio.h>addition(int x, float y){    float ans;    ans = (float)x + y;    printf("Answer : %.2f",ans);}int main(){   int a;   float b;   printf("enter first number : ");   scanf("%d",&a);   printf("enter second number : ");   scanf("%f",&b);   addition(a, b);}`
`//C++ Program//Sum of two numbers using function#include<stdio.h>using namespace std;//function to add two numbersfloat sum(int a, float b){	return (float)(a+b);}//main programint main(){	//initialising variables	int a;	float b;	cout<<"Enter two numbers";	//user input	cin>>a;	cin>>b;	//call function to find sum	cout<<"Sum of "<<a<<" and "<<b<<" is "<<sum(a,b);	return 0;}`

#### Output

`Enter two numbers 1098.43Sum of 10 and 98.43 is 108.43`
`import java.util.Scanner;class Main{	public static void main(String[] args)	{		Scanner sc = new Scanner(System.in);		System.out.print("Number 1 : ");						int num1 = sc.nextInt();		System.out.print("Number 2 : ");						float num2 = sc.nextFloat();		float sum = num1 + num2;		System.out.println("Sum = "+sum);	}}`

This series is a mixture of 2 series all the odd terms in this series form even numbers in ascending order and every even terms is derived from the previous  term using the formula (x/2)

Write a program to find the nth term in this series.

The value n in a positive integer that should be read from STDIN the nth term that is calculated by the program should be written to STDOUT. Other than the value of the nth term no other characters /strings or message should be written to STDOUT.

For example if n=10,the 10 th term in the series is to be derived from the 9th term in the series. The 9th term is 8 so the 10th term is (8/2)=4. Only the value 4 should be printed to STDOUT.

You can assume that the n will not exceed 20,000.

`Code:#include<stdio.h>int main() {//codeint n;scanf(“%d”, &n);if(n % 2 == 1){int a = 1;int r = 2;int term_in_series = (n+1)/2;int res = 2 * (term_in_series – 1);printf(“%d “, res);}else{int a = 1;int r = 3;int term_in_series = n/2;int res = term_in_series – 1;printf(“%d “, res);}return 0;}`

TCS Coding Section used to be based on Command Line Argument based Coding Questions it is available no where else on the internet. We will try help you with learning command line argument based coding for TCS.

From this year there is no command Line programming but you have to use C, C++, Java, Python and Perl. We have the latest set of questions for the new pattern

Question 0

Find the nth term of the series.

1,1,2,3,4,9,8,27,16,81,32,243,….

`#include <stdio.h>#include <string.h>int three(n){int x,i;for(i=0;i<100;i++){x=pow(3,i);if(i==n)printf("%d",x);}}int two(n){int x,i;for(i=0;i<100;i++){x=pow(2,i);if(i==n)printf("%d",x);}}int main(){int n;scanf("%d",&n);if(n%2==0)three(n/2);else two(n/2+1);}`

• Cut-off – Solve 1 question completely or partial output

Though command Line Programming is not there you should study it for C MCQ section as 1-2 MCQ would be there for command Line program.

### TCS C Command Line Programming Basics

• Keywords like getc, scanf, getch, getchar etc can not be used.
• Instead we use command line arguments to fetch values.

Before reading further for TCS Coding Round Questions, I will suggest not to freak out if you don’t understand in first go. Read everything once and then when you read again things will start to make sense. It is the best resource on the internet to know about TCS command line Argument Type Questions and TCS C Programming Questions and Answers.

#### TCS Coding Questions with Answers

Let us consider this, if you wanted to write a basic C program then you would’ve written a main function that would’ve looked like in compiler for TCS Coding Round Questions –

`int Main(){`

// some code

}}

However in command line arguments we write like this –

int main(int argc, char *argv[]){

• argc – It is known as Argument Count and as clear from the name it stores the Count of number of Arguments.
• argv[] – Pointer, contains location of all the values(arguments).
• *argv[] – Array of values of all the arguments.
• They are parameters/arguments supplied to the program when it is invoked.

Thus, now we have two things

1. Total Count of number of Arguments.
2. All the values/pointer location of arguments stored in an array.

Now, you will need one more thing i.e. atoi();

• atoi(); – Converts string into int and atoi(argv[i]); will give the value of argument at ith location in int type format.

Now you can use an int val = atoi(argv[i]); to store the value and then print it with printf(); function.

Check out this video Below to learn how to Solve Command Line Programming.

Quick Facts

argv contains the name, not the value so –

• All for loops must start from i=1.
• You must use the following condition

if(argc == 1){

// do nothing since, there are no arguments, maybe ask for arguments?

}else{

// code to apply logic and print values in TCS Coding Round Questions.

}

• provided+1 +1 for file.exe
• argv[argc] is a NULL pointer.
• argv holds the name of the program.
• argv points to the first command line argument and argv[n] points last argument.

Command Line Arguments here – Read this properly.

```// Program to print all value of
// command line argument
// once we get the value from command
// line we can use them to solve our problem.
#include<stdio.h>  // this is used to print the result using printf
#include<stdlib.h>  // this is used for function atoi() for converting string into int

// argc tells the number of arguments
// char *argv[] is used to store the command line
//arguments in the pointer to char array i.e string format
int main(int argc, char *argv[])
{
// means only one argument   exist that is file.exe
if (argc == 1) {
printf("No command line argument exist Please provide them first \n");
return 0;
}

else {
int i;
// actual arguments starts from index 1 to (argc-1)
for (i = 1; i < argc; i++) {
int value = atoi(argv[i]);
// print value using stdio.h library's printf() function
printf("%d\n", value);
}
return 0;
}
}```

## TCS Programming Test FAQ's

### What is the level of difficulty of the question asked in TCS programming round?

Ans. They are easy but you need to have good grip over basic C/C++ input/output or pattern based programs.

Logics like Recursion, For loops, If loops etc

### What languages can we use in TCS Coding Round Questions?

Ans. In TCS Coding Round Questions currently you can only use C/C++ and Java for coding in TCS based Compiler that is mostly GCC type of compiler.

### Is PrepInsta enough to prepare for TCS Coding Round and Questions asked in the exams?

Ans. Yes, it is the best resource out there in the internet to prepare for TCS Coding section paper.

#### Rules for TCS Coding Round Questions Section:

• There is only one question for 20 minutes.
• It has 10 attempts(We can compile only 10 times).
• We must start our code from the scratch.
• The coding platform is divided into two, one for writing the code and other for output. We should write the whole
program.
• We must only print exact output.
• Output must not be re-framed by extra words.
• If there is any error, the error will be shown in the output dialog box.
• The errors are clearly mentioned.
• If there are no errors, a message like “compiled successfully” will be printed.
• Along with that they will mention four test cases are ‘passed’ or ‘failed’. They are indicated like private and public test cases. They have not mentioned what is the test case, which is difficult to understand.

Don’t Compile again and again since compiler takes 25 seconds and each time you compile 25 seconds will become lesser in the time you have to code in TCS Placement Papers Programming.

### How to clear the TCS coding round?

Ans. First you must learn command line programming from our coding dashboard and then try sample questions given on the dashboard to know how to clear the tcs coding round  and TCS C Programming Questions and Answers

### What are some other websites where we can find more questions?

Ans. You can find more questions on MyGeekMonkey website.
