} object-list;

class employee {
   char         name[80];
   double       wage;

public:
   void putname (char *n);
   void getname (char *n);
   void putwage (double w);
   double getwage();
};

A class is a logical abstraction, but an object has physical existence.

access-specifier can be:

`public`:
Allow functions or data to be accessible to other parts of the program.

`private`:
May be accessed only by other members of the class.

`protected`:
Used when inheritance is involved; discussed later.
