The difference between member function and friend function is that the member function takes argument ex-plicitly.On the contrary, the friend function needs the parameters to be explicitly passed. Operator overloading provides an inherent interface to the users of our class, making it possible to work equally well with classes and built-in data types. You use binary operators very frequently like addition (+) operator, subtraction (-) operator and division (/) operator. Below are some criteria/rules to define the operator function: In case of a non-static function, the binary operator should have only one argument and unary should not have an argument.
