One of the nice features of C++ is that you can give special meanings to operators, when they are used with user-defined classes. This is calledoperator overloading. You can implement C++ operator overloads by providing special member-functions on your classes that follow a particular naming ...

Class member access can be controlled by overloading the member access operator (–>). This operator is considered a unary operator in this usage, and the overloaded operator functionmust be a class member function. Therefore, the declaration for such a function is: class-type*operator–>() ...
See General Rules for Operator Overloading for more information. The constraints on the various categories of overloaded operators are described in the following topics: Unary Operators Binary Operators Assignment Function Call Subscripting Class-Member Access Increment and Decrement. User-Defined...
Considerations in Using Operator Overloading Conclusion Introduction Operator overloading is a powerful tool that allows you to redefine many operators (addition, subtraction, and so on) within classes and structures, making them more useful and relevant to the class or structure in question. With ...
Learn how to overload a C# operator and which C# operators are overloadable. In general, the unary, arithmetic, equality and comparison operators are overloadable.
Unary operators The following example shows the syntax to overload all the unary operators, in the form of both global functions (non-member friend functions) and as member functions. These will expand upon the Integer class shown previously and add a new byte class. The meaning of your parti...
Operator overloading involves many concepts, some of which will be covered later in the book (templates,auto ref, etc.). For that reason, you may find this chapter to be harder to follow than the previous ones. Operator overloading enables defining how user-defined types behave when used ...
When a user-defined class overloads the function call operator operator(), it becomes a FunctionObject type. An object of such a type can be used in a function call expression: // An object of this type represents a linear function of one variable a * x + b. struct Linear { ...
