As with any assignment operator overloading, we must return a dereferenced this pointer at the end. To define a move assignment operator outside the class, we use: Copy classMyClass//www.java2s.com{public: MyClass&operator=(constMyClass& rhs); }; MyClass& MyClass::operator=(constMyClas...

Introduction The assignment operator = assigns a value to a variable / object: intmain()/*fromwww.java2s.com*/{charmychar ='c';// define a char variable mycharmychar ='d';// assign a new value to mycharintx = 123;// define an integer variable xx = 456;// assign a new value ...
The default behavior of this operator function is to perform a member-wise copy assignment of the object's non-static data members and direct base classes; however, this behavior can be modified using overloaded operators. For more information, see Operator overloading. Class types can also ...
Make sure that the assignment operator overload returns a reference tothis. Define a separate function if the desired assignment operator differs significantly from the default behavior. Example¶ classB{B&operator=(constB&other){...//incorrect, does not return a reference to this}};classC{C...
Overloading a binary operator implicitly overloads its corresponding assignment operator (if any). The different assignment operators are based on the type of operation performed between two operands such as addition (+=), subtraction, (-=), etc. The meaning of the operator symbol used depends...
This is called overloading, as it gives another definition for an existing function. Which function is used (the built-in or user-defined) depends on the context, which means the types of the arguments that are used in the expression. In addition to the operator functions, it is also ...
