Define generic comparison operator

Question

I came up with the idea to define a generic comparison operator which would work with any type, for the fun of it.

#include 
#include 

        

Answer 1

Let's take a perfectly normal class, say String. It's implemented as you'd think, with a char* that points to a new[]'ed buffer.

Now compare two of them. Obviously, String("abc")==String("abc"). Yet your implementation fails this test, as the two pointers differ.

Equality is defined by the class semantics, not by the bits directly inside the object.
