Question 10

Chatbots are now part of the cultural narrative and are becoming even more sophisticated. It is hard to find someone who has not had an interaction with a chatbot or virtual assistant. As chatbots and virtual assistants get more sophisticated, they will be able to respond with increasing empathy and personalization, seamlessly tracking the customer journey. Whether voice or text activated, bots will be able to help users find products and answers 24 X 7, on any device or channel faster than ever before. In fact, more and more people are rating messaging as a top choice for customer service.

Question – 2

Link to this Question

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>
#include<math.h>

int main() {
//code
int n;
scanf(“%d”, &n);
if(n % 2 == 1)
{
int a = 1;
int r = 2;
int term_in_series = (n+1)/2;
int res = pow(2, term_in_series – 1);
printf(“%d “, res);
}
else
{
int a = 1;
int r = 3;
int term_in_series = n/2;
int res = pow(3, term_in_series – 1);
printf(“%d “, res);
}

return 0;
}

return 0;
}

Question 3

Link to this Question – 

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.

Code:

#include <stdio.h>
#include<math.h>

int main() {
//code
int 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;
}

Question 5

Link to this Questions

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

Write Code for this

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
int main()
{
char *str1=malloc(sizeof(char)*256);
char *str2=malloc(sizeof(char)*256);
char *str3=malloc(sizeof(char)*256);
printf(“ENter 3 words : “);
scanf(“%s%s%s”,str1,str2,str3);

int p1=strlen(str1);
int p2=strlen(str2);
int p3=strlen(str3);
for(int i=0;i<p1;i++)
{
if(str1[i]==’a’||str1[i]==’e’||str1[i]==’i’||str1[i]==’o’||str1[i]==’u’)
{
str1[i]=’$’;
}
}
for(int i=0;i<p2;i++)
{
if(str2[i]!=’a’ && str2[i]!=’e’ && str2[i]!=’i’ && str2[i]!=’o’ && str2[i]!=’u’)
{
str2[i]=’#’;
}
}
for(int i=0;i<p3;i++)
{
str3[i]=str3[i]-32;
}

printf(“\n%s”,str1);
printf(“\n%s”,str2);
printf(“\n%s”,str3);

return 0;

Question 7

Link to this code is here

look at the series below: 1,2,3,5,8,13,21,34,55,89,144,233,377,610,987,…..

This series is formed as below: 1.term(1)=1

2.term(2)=2

3.term(N)=term(N-1)+term(N-2)for N>2

Write a program to find the Nth term in this series .the value N is 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 nth term no other characters /strings and messages should be written to STDOUT.

For example if N =15,the value of 15thn term is 987 which is the sum of 13th and 14th terms . You can assume that the value of n will not exceed 30

Ans:

#include <stdio.h>

int main() {

//code int n;

scanf(“%d”, &n);

if(n == 1)

{

printf(“1”);

}

else if(n ==2)

{

printf(“2”);

}

else

{

int t1=1, t2=2, nth_term; for(int i = 3; i <=n; i++)

nth_term = t1 + t2; t1 = t2;

t2 = nth_term;
