The C++ Version: Part 1

private: // private members: class access only

char *name;

int base_pay;

int year_started;

int leave_time;

public: // public members: anyone can access

// This is a constructor: the only way

// to create a new instance of this class

employee(char *n, int pay);

// This is a destructor: always called

// when the instance goes away

~employee();

};

employee::employee(char *n, int pay)

{

name = strdup(n);

base_pay = pay;

year_started = current_year();

leave_time = 0;

}

employee::~employee()

{

free(name);

}

Note that “public” members deal with the interface whereas “private” members deal with the implementation; strong division

We enforce the fact that new employees must have a name and base pay; leave time must be 0 and year started must be now

We enforce that memory is allocated for name when it’s created and destroyed when done
