Predict the output of the below program:
#include <iostream>
using namespace std;
#define EVEN 0
#define ODD 1
int main()
{
int i = 3;
switch (i & 1)
{
case EVEN: cout << \"Even\";
break;
case ODD: cout << \"Odd\";
break;
default: cout << \"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.
