Why is the output of the program is 0.

Question

#include <iostream>
using namespace std;

int main() {
int x;
int y=2;
cout<<x%y;
return 0;
}

Answer 1

It seems SL compiler sets variable x (which is uninitialized) to 0. So, 0 % 2 gives you 0.
But it's a good practice to initialize your variable to something meaningful. (e.g. int x = 0;)
