Tag: Operator overloading

The postfix increment operator ++ can be overloaded for a class type by declaring a nonmember function operator operator++() with two arguments, the first having class type and the second having type int . Alternatively, you can declare a member function operator operator++() with one argument having type int .

In C++, we can change the way operators work for user-defined types like objects and structures . This is known as operator overloading. For example, Suppose we have created three objects c1 , c2 and result from a class named Complex that represents complex numbers.

It is polymorphism in which an operator is overloaded to give user defined meaning to it . Overloaded operator is used to perform operation on user-defined data type. For example ‘+’ operator can be overloaded to perform addition on various data types, like for Integer, String(concatenation) etc.
