#include <stdio.h>#define EVEN 0#define ODD 1int main(){ int i = 3; switch (i & 1) { case EVEN: printf("Even"); break; case ODD: printf("Odd"); break; default: printf("Default"); } return 0;} |
(A) Even
(B) Odd
(C) Default
(D) Compile-time error
Answer: (B)
Explanation: The expression i & 1 returns 1 if the rightmost bit is set and returns 0 if the rightmost bit is not set. As all odd integers have their rightmost bit set, the control goes to the block labeled ODD.
