Operator Overloading

Operators in C++ may be overloaded in the same way that functions are overloaded. Most operators may be overloaded both binary and unary operators.

UNIT III: Operator Overloading: Overloading Unary – Binary

Overloading is an important feature of c++. • It is similar to function overloading. An operator is a symbol used for an operation. • C++ has the ability to 

Unit IV: Operator Overloading and Type Conversions

can overload all the C++ operators except the following: - Class member access operators ( . Unary operator overloading means it takes only one operand.

Introduction to C++ Operator Overloading - Computer Action Team

Overloading operators as non-member functions is like defining regular C++ functions Since they are not part of a class' definition they can only access the public members Because of this non-member overloaded operators are often declared to be friends of the class

Operator Overloading in C++

Overloading unary operators of a class: – Can overload as a non-staticmember function with no arguments – Can overload as a global function with one argument • Argument must be class object or reference to class object – Remember staticfunctions only access staticdata Systems Programming: Operator Overloading 2222

A Summary of Operator Overloading - University of Michigan

A non-member operator overload function is just an ordinary function that takes at least one argument of class type and whose name is of the form operator op A non-member operator overloading function simply has the operator function name and does whatever you want with the lhs and rhs parameters For example suppose we have a simple

How do you overload a unary operator?

You overload a unary operator with either a nonstatic member function that has no parameters, or a nonmember function that has one parameter. Suppose a unary operator @ is called with the statement @t, where t is an object of type T .

How to define overloaded operators?

?There are 3 ways to define overloaded operators: 1. Member function 2. Nonmember function 3. Friend function Member function ?The first way is by class method(member function). This is the most popular way. Many experts advocate always overloading operators as member operators rather than as nonmembers.

How to overload a binary operator for user-defined types?

Here, + is a binary operator that works on the operands num and 9. When we overload the binary operator for user-defined types by using the code: The operator function is called using the obj1 object and obj2 is passed as an argument to the function. Instead of this, we also could have written this function like:

What is an example of a unary operator?

Unary operators operate on only one operand. The increment operator ++ and decrement operator -- are examples of unary operators. Here, when we use ++count1;, the void operator ++ () is called. This increases the value attribute for the object count1 by 1.
