測試版OO (or OOP) has been used to mean “Object-Oriented (Programming)” for several decades, but there is another use of the acronym OO which is: “Operator Overloading”. Simply put this involves creating (concrete) classes (or types) for which some (or rarely, most, or even all) C++ operators are redefined in terms of functionality related to the class.
