Predict the output of below program:
#include <stdio.h>
int main()
{
    printf("%c ", "GeeksQuiz"[5]);
    return 0;
}

                    
(A) Compile-time error (B) Runtime error (C) Q (D) s

Answer: (C)

Explanation: The crux of the program lies in the expression: “GeeksQuiz”[5]. This expression is broken down by the compiler as: *(“GeeksQuiz” + 5). 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.
