public:  A public data can be accessed by outside of the code in which it is defined.

private: A private data can not be accessed by outside of the code in which it is defined. The private data can be accessed by only member function 

protected: A protected access control is similar to the private only difference is that it has a access to their derived classes. Protected applies only when inheritance outside.
