class, private, and public are key words.

A class usually has two types of members: data fields and methods.Data fields should always be private!Method can be private or public. (We will explain this later.)class ClassName{private: DataMemberList; MethodMemberList1;public: MethodMemberList2;};Class Objectclass Student{private: long id; string firstName; ...};
