C | Operators | Question 8

#include <stdio.h>
int main()
{
    //Assume sizeof character is 1 byte and sizeof integer is 4 bytes
    printf("%d", sizeof(printf("GeeksQuiz")));
    return 0;
}

(A) GeeksQuiz4
(B) 4GeeksQuiz
(C) GeeksQuiz9
(D) 4
(E) Compile-time error


Answer: (D)

Explanation: An expression doesn’t get evaluated inside sizeof operator. GeeksQuiz will not be printed. printf returns the number of characters to be printed i.e. 9 which is an integer value. sizeof operator returns sizeof(int).
