Types of Operator Overloading in C++ - GeeksforGeeks

Operator Overloading can be done by using two approaches, i.e. Overloading Unary Operator. Overloading Binary Operator. Criteria/Rules to Define the Operator Function. In the case of a non-static member function, the binary operator should have only one argument and the unary should not have an argument.

The stream operators, among the most commonly overloaded operators, are binary infix operators for which the syntax does not specify any restriction on whether they should be members or non-members.

Overloading unary and binary operators - diginode.in

Unary operators operate on a single operand. Examples include increment (++), decrement (–), logical NOT (!), and unary minus (-). Unary operators can be overloaded as member functions or as standalone functions. Let’s explore an example of overloading the unary minus (-) operator for a custom class Vector.

General Rules for Operator Overloading | Microsoft Learn

Binary operators declared as member functions take one argument; if declared as global functions, they take two arguments. If an operator can be used as either a unary or a binary operator (&, *, +, and -), you can overload each use separately. Overloaded operators cannot have default arguments.

Operator overloading : member function vs. non-member function?

Not all overloaded operators are restricted to a single parameter. The () operator can take any number of parameters. Unary operators, on the other hand, can't have any parameters. By C++23, operator[] is also allowed to be overloaded as a member function with more than one parameter.

In C (also C++), how '&' operator works as both address operator and ...

So basically the "&" operator has different meaning when used as a unary operator and as a binary operator operator. The same goes for various other operators like, " * " , " - ", etc. It has simple different meanings when applied to the lvalue (it the unary operator in this case) or when it is used in the math expression with two operands.

Operator overloading in C++ - Educative

Operator overloading is the power of a programming language that allows the built-in operators (+ +, - −, * ∗, etc.) to be overloaded for user-defined data types. The familiarity of the symbols for an expected behavior facilitates reading and writing. The cascading of multiple function calls is easy to understand in expressions.
