ISRO | ISRO CS 2020 | Question 36

What is the output of the code given below?

#include <stdio.h>
int main( )
 {
   char name[ ]=“satellites”;
   int len;
   int size;
   len = strlen(name);
   size = sizeof(name);
   printf(“%d”, len * size);
   return 0;
 }

(A) 100
(B) 110
(C) 40
(D) 44

Answer: (B)
Explanation: Note –

• strlen() function returns length of string without null character.
• sizeof() function returns size of string with null character.
• sizeof() = strlen() + 1

Therefore, 110 will be printed.

#include <stdio.h>
#include <cstring>

int main( )
 {
   char name[ ]="satellites";
   int len;
   int size;
   len = strlen(name);
   size = sizeof(name);
   printf("%d", len * size);
   return 0;
 }

Option (B) is correct.
