OVERLOADING BINARY PLUS (+) WITH OPERATOR FUNCTION AS MEMBER FUNCTION || C++ PROGRAMMING -Lecture-3

Binary operators like +, - and / take two operands to work. These operators may be defined as member or friend functions.
If they are overloaded as a member function, binary operators require one argument. The argument contains value of the object, which is to the right of the operator.
To overload a binary operator + use operator function as a member function within the class.
The operator function of binary plus (+) with in the class is defined as:
Class-name operator +(Class-name object) {
// Perform the addition on different values of objects and return the result
}
The return-type is Class-name because the operator function returns the resultant object.
The operator function call is made when it is used as object3 = object1 + object2; and the system will call object3 = object1.operator +(object2);
