Answer 1

double prompt(string input ) {
    double input;
    cin>>input;
    return input;
}

String is called input and double is called input…. there is something wrong here.

Surely this should be something like:

double prompt(string promptStr)
{
    double input;
    cout << promptStr;
    cin >> input;
    return input;
}
