The related operators are expected to behave similarly ( operator+ and operator+ = do the same addition- like operation). Overloading addition assignment operator. For example string concatenation list appending.
Much of the work in a program is done by evaluating expressions such as assignments to variables, either for their side effects for their. & = Bitwise assign. All four of these operators are overloaded in the exact same way.


The canonical forms of the free function versions of the operators are as follows: / / Assignment operators: Type & operator& = ( Type & lhs const Type & rhs) ; / / Assign bitwise , Type & operator^ = ( Type & lhs const Type & rhs) ;. There are all sorts of classes for which arithmetic assignment operators ( addition, whether you are using them for math , left/ right bit shift) make sense, multiplication, modulo something else.


These are both convenient and efficient. It is natural to assume at first glance that overloading ` = ' means that you' re overloading assignment for the class in question. 2 It defines a Person * d_ data pointer so it offers a copy constructor an overloaded assignment operator.
