Assume that a character takes 1 byte. Output of following program?

#include<stdio.h>
int main()
{
    char str[20] = \"GeeksQuiz\";

    return 0;
}

9
 

(B)

10
 

(C)

20
 

(D)

Garbage Value
 


Answer: (C)

Explanation:

Note that the sizeof() operator would return size of array. To get size of string stored in array, we need to use strlen(). The following program prints 9. 

 

#include <stdio.h>
#include <string.h>
int main()
{
    char str[20] = \"GeeksQuiz\";
    printf (\"%d\", strlen(str));
    return 0;
}
