Overloaded operators. When an operator appears in an expression, and at least one of its operands has a class type or an enumeration type, then overload resolution is used to determine the user-defined function to be called among all the functions whose signatures match the following:

Operator overloading is not available in C. Instead, you will have to use a function to "pseudo-overload" the operators: Colour add_colours(Colour c1, Colour c2) { return c1 + c2; // or whatever you need to do }

The name of an overloaded operator is operator x, where x is the operator as it appears in the following table. For example, to overload the addition operator, you define a function called operator+. Similarly, to overload the addition/assignment operator, +=, define a function called operator+=.

Operator Overloading is a feature in some programming languages used to redefine or “overload” the standard behavior of operators (such as +, -, *, etc.) to work with user-defined data types. This is useful when working with objects of custom classes.

By overloading standard operators on a class, you can exploit the intuition of the users of that class. This lets users program in the language of the problem domain rather than in the language of the machine. The ultimate goal is to reduce both the learning curve and the defect rate.

There are two overarching purposes of operator overloading. First, operator overloading enables your custom classes to act like primitive types. That is, if you have a class like vector that mimics a standard C++ array, you can allow clients to use array notation to access individual elements.

Overloads of operator new and operator new[] with additional user-defined parameters ("placement forms", versions ) may be declared at global scope as usual, and are called by the matching placement forms of new expressions.

In detail, overload resolution proceeds through the following steps: Building the set of candidate functions. Trimming the set to only viable functions. Analyzing the set to determine the single best viable function (this may involve ranking of implicit conversion sequences).

To overload an operator is to provide it with a new meaning for user-defined types. This is done in the same fashion as defining a function. The basic syntax follows (where @ represents a valid operator): return_type operator@(parameter_list) { // ... definition }
