What will be the output of the program ?
#include <stdio.h>
#include <string.h>
int main()
{
char str[] = "India\0\BIX\0";
printf("%d\n", strlen(str));
return 0;
}
Answer: C
Correct answer: 5
strlen stops at the first null, and the initialiser puts one immediately after India. So the count is 5, even though the array holds several more characters. Compare sizeof, which would report the whole array.
