Changing function based on a condition?

[Lindley]

Actually, there may be an even better way to design the function because it's more "self-documenting":

		studio = getData("studio");
		oneBed = getData("one-bedroom");
		twoBed = getData("two-bedroom");

int getData(const std::string &apttype)
{
        int num;
        cout << "How many " << apttype << " apartments?: ";
        cin >> num;
        return num;
}

Again we could have used a const char* rather than a std::string const reference, but in this case it isn't *quite* the same-----this way allows you to pass either a char* in or a string object.
