Have you heard of these things called compilers? They're great for figuring this sort of thing out. Run the code if you can't logic it out.

It is clear the code is not in the right form.

Here might be a working code:

#include <iostream>

using std::cout;
using std::endl;

void Twist(int a, int &b)
{
    int c;
    c = a - 2;
    a = a * 3;
    b = c + a;
}

int main(void)
{
    int r, s, t;
    r = 1;
    s = 2;
    t = 3;
    Twist(t, s);
    cout << r << ' ' << s << ' ' << t << endl;
    return 0;
}
