Hi! I'm asked to add more variables (3 and 4) to my C++ code. I only made with 2, can someone help me?

Question

#include <iostream>
using namespace std;
int main()
{
    int n, m;
    cin >> n >> m;
    while(n != m)
        if(n > m)
            n -= m;
        else
            m -= n;
    cout << n << endl;
    return 0;
}

Answer 1

What are you trying to accomplish? If you want to add more variables that is:

    int n{}, m{},p{},q{};
    std::cin >> n >> m>>p>>q;
