By default all the members of a class would be private,The private data members cannot be accessed from outside the class. They can only be accessed by class or friend functions. All the class members are private by default.When preceding a list of class members, the private keyword specifies that those members are accessible only from member functions and friends of the class. This applies to all members declared up to the next access specifier or the end of the class.A function declared inside the private access specifier of the class, is known as a private member function.
