Trying to compare members of different classes to identify which is larger? Any ideas?

[umbral ore]

This is what I've got so far. It works great, except I need help figuring out how to use the operator> overload via different classes. Can anyone help? https://godbolt.org/z/arsqWK5qE

Overloading the Less Than Operator

The less than operator returns true iff one object less than the other. If it establishes a strict weak ordering, it makes a type LessThanComparable, which allows using the type in a std::map, in std::sort and other algorithms.

Example

struct point {
    int x, y;
    // explicit defaulting since C++20
    bool operator>(const point&) const = default;
};
// can also be defined outside the class
bool operator<(point a, point b) {
    return a.x < b.x ||
           a.x == b.x && a.y < b.y;
} ```
