Quick Facts

argv[0] 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[0] holds the name of the program.
• argv[1] points to the first command line argument and argv[n] points last argument.

// 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  // this is used to print the result using printf
#include  // 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 Based FAQ’s

Ques. 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

Ques. 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.

Ques. 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 can’t use any input functions like scanf(), getch(), getchar().
• The input to be provided should be read as command line arguments.

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.

Ques. 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

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

Ans. You can find more questions on MyGeekMonkey website here – http://mygeekmonkey.com/tcs-coding-questions.html
