Characteristics of Member Functions
- The difference between member and normal function is that the formal function can be invoked freely, whereas the latter function only by using an object of the same class.
- The same function can be used in any number of classes. This is possible because the scope of the function is limited to their classes and cannot overlap one another.
- The private data or private function can be accessed by public member function. Other functions have no access permission.
- The member function can invoke one another without using any object or dot operator.
