The C++ Version: Part 2

class employees {

private:

class employee *c_employees[MAX_EMPLOYEES];

int num_employees;

public:

employees(void) { num_employees = 0; }

int add_employee(char *name, int pay);

~employees();

};

int employees::add_employee(char *name, int pay)

{

if (num_employees >= MAX_EMPLOYEES) {

return an error;

} else {

c_employees[num_employees++] =

new employee(name, pay);

return 1;

}

}

• num_employees guaranteed to be initialized

• Bounds checking inherent to the class employees

• Note use of “new” that can pass args to the constructor

• No one can touch our private data

• We could write a destructor that deallocates all allocated memory
