Public:  Public members can be access through any object of that class. We can access public data anywhere in the program means in the class also and main also.
Private: We can access private data within that class only not outside of that class means not in the main. All data and methods of class are private by default.
Protected: v A member declared as protected is accessible by the member functions within its class and by the any class immediately derived from it.
