如何在C ++中适当地将>运算符重载为模板函数？ 学习模板重载

Question

I want to do a regular operator overload, but with templates. So imagine:

template <typename Type>
bool operator> (Type &tX, Type &tY)
{
     return (tX.data > tY.data) ? tX : tY;
}

But I want it to work with any class or primitive. What is wrong with the code?

Answer 1

How can I properly overload the > operator as a template function in C++?

1. You cannot overload the > operator for primitive types. The language does not allows that.

2. You cannot overload the > operator for user defined types in any sensible manner either. The generic implementation has no way of knowing how one instance of a user defined type can be compared with another instance of the same type.
