Question

This seems trivial yet endless searching doesn’t yield an answer.

I need to compare and assign.

How can I overload the COORD if I can’t add a member function or friend a function?

is it just bad style to use this windows based structure?

Also, I know I can write my own class(or just do the operation once for each member), but this problem just really has me wondering.

Answer 1

COORD only has public members, so there’s no need for friend functions — free operators should suffice:

bool operator <(COORD const& lhs, COORD const& rhs)
{
    return lhs.Y < rhs.Y || lhs.Y == rhs.Y && lhs.X < rhs.X;
}

bool operator ==(COORD const& lhs, COORD const& rhs)
{
    return lhs.X == rhs.X && lhs.Y == rhs.Y;
}

COORD has an implicit copy c’tor and operator= already, no need to define those.
