op is the operator to be overloaded. Operator Overloading can be done by using three approaches, i.e. Overloading unary operator. Overloading binary operator. Overloading binary operator using a friend 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.
Can a member function be overloaded?
Many operators can be overloaded in a different way: as a member function. Overloading operators using a member function is very similar to overloading operators using a friend function. When overloading an operator using a member function: The overloaded operator must be added as a member function of the left operand.
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.In the case of a friend function, the binary operator should have only two arguments and the unary should have only one argument.All the class member objects should be public if operator overloading is implemented.Operators that cannot be overloaded are .* :: ?:

Overloading Unary Operator
Let us consider overloading (-) unary operator. In the unary operator function, no arguments should be passed. It works only with one class object. It is the overloading of an operator operating on a single operand. Example: Assume that class Distance takes two member objects i.e. feet and inches, and creates a function by which the Distance object
Overloading Binary Operator
In the binary operator overloading function, there should be one argument to be passed. It is the overloading of an operator operating on two operands. Below is the C++ program to show the overloading of the binary operator (+) using a class Distance with two distant objects. Explanation: 1. Line 27, Distance operator+(Distance &d2):Here return typ
Overloading Binary Operator Using A Friend Function
In this approach, the operator overloading function must be preceded by the friendkeyword, and declare the function in the class scope. Keeping in mind, the friend operator function takes two parameters in a binary operator and varies one parameter in a unary operator. All the working and implementation would same as the binary operator function ex
