Q. What will be the output of the following C program?

Code:
#include <stdio.h>

int main()
{
    printf(\"%c \", 5[\"GeeksQuiz\"]);
    return 0;
}
(A) Compile-time error
(B) Runtime error
(C) Q
(D) s

Explanation:

The crux of the program lies in the expression: 5["GeeksQuiz"] This expression is broken down by the compiler as: *(5 + "GeeksQuiz"). Adding 5 to the base address of the string increments the pointer(lets say a pointer was pointing to the start(G) of the string initially) to point to Q. Applying value-of operator gives the character at the location pointed to by the pointer i.e. Q.
