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.

What are the basic rules and idioms for operator overloading?

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

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.

UNIT III: Operator Overloading: Overloading Unary – Binary Operators ...

• Overloaded Operators are redefined using Operator followed by an Operator symbol. An Operator function should be either a member function or Friend function. A Friend Function requires one argument for unary operators and two for binary Operators. A Member function requires one argument for binary operator and no arguments for unary Operators.

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.

C++ Operator Overloading Explained | Medium

To overload a unary operator, you define a member function with no parameters or a non-member function with one parameter. Example: Overloading the unary - operator:

C++ Operator Overloading (Uniray & Binary Operators) | Trytoprogram

In this article, you will learn in depth about C++ operator overloading and its types with corresponding examples. In C++ the meaning of existing operator can be extended to operate on user-defined data or class data. C++ has the ability to prove the operators with a special meaning for a data type.

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 : 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.
