Why do you want to store references?
maharris (85)
to have them appear later in the program. i want to have the user write them, then later read them.
Peter87 (11188)
I don't understand what you say but you can use references if you initialize them in the constructor initializer list

	int& monthChange;
	int& weekChange;
	int& dayChange;
};

rateChange::rateChange(int& mc, int& wc, int& dc)
:	monthChange(mc),
	weekChange(wc),
	dayChange(dc)
{
};
