C | Input and Output | Question 5

Predict the output of the below program:

C

#include <stdio.h>

int main()
{
    printf(\"%c \", 5[\"GeeksQuiz\"]);
    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: 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.
