Complete Modern C++ - Operator Overloading - Part I (Basics)

The video tutorial explains operator overloading, a technique to provide custom implementations of operators for user-defined objects, allowing them to be used in complex expressions. It covers the syntax and implementation of overloaded operators as both global and member functions, using the plus operator as an example. The tutorial also discusses debugging, resolving ambiguities, and the efficiency of pre and post increment operators. Finally, it demonstrates overloading a comparison operator to check equality between objects.
