Pointers to Classes

private:

int year_p, month_p, day_p;

public:

// For the sake of example, let’s define a “date” class that

// has NO DEFAULT CONSTRUCTOR; arguments are required.

date(int day); // Constructor that takes one arg

date(int month, int day); // Another overloaded constructor

date(int year, int month, int day); // And another

date(char *datestring); // And another

};

date today; // Illegal -- no constructor w/ no args!

date jan1(1, 1); // Legal -- second constructor called

date *pa, *pb // These are LEGAL -- they are just pointers to

// dates, not actual instances of dates - the

// constructor is not called

pa = &jan1; // pa now points to jan1

pb = malloc(sizeof(date));// Is this correct? How do we pass args

// to a constructor while allocating mem?
