Error while overloading operator (must be a nonstatic member function)

Question

I\'m writing string class on my own. And I have such code. I just want to overload operator=. This is my actual code, and I get error in last part of code.

Answer 1

You are missing class name:

This is global operator, = cannot be global:

S &operator=(const S &s)

You must define this as class function:

S & S::operator=(const S &s)
