When an operator appears in an expression, and at least one of its operands has a class type or an enumeration type, then overload resolutionis used to determine the user-defined function to be called among all the functions whose signatures match the following: Note: for overloading co_await, (since C++20)user-defined conversion functions, user-de...
The operators :: (scope resolution), . (member access), .* (member access through pointer to member), and ?:(ternary conditional) cannot be overloaded.New operators such as **, <>, or &|cannot be created.It is not possible to change the precedence, grouping, or number of operands of operators.The overload of operator -> must either return a raw pointer, or return an object (by reference or by value) for which operator ->is in turn overloaded.Besides the restrictions above, the language puts no other constraints on what the overloaded operators do, or on the return type (it does not participate in overload resolution), but in general, overloaded operators are expected to behave as similar as possible to the built-in operators: operator+ is expected to add, rather than multiply its argum...
