Convert Decimal to Binary using Bitwise Operators in C++

#include <bits/stdc++.h>

using namespace std;

void ConvertToBinary(int n) {
    // size of the integer is assumed to be 32-bits
    for (int i = 31; i >= 0; i--) {
        int k = n >> i; // shifts all bits rightwards i times
        cout << (k & 1 ? '1' : '0') << " ";
    }
}

int main() {
    int n = 13;
    ConvertToBinary(n);
    cout << '\n';
    return 0;
}
