Operator Overloading◀ Inline Function▶ Operator Overloading for Member Functions Amazon
perator overloading is perhaps one of the most powerful tools that C++ provides. The idea is to make an operator work with multiple data types. For example, cout
is a heavily overloaded function because you can use it to output an int
