My main problem is part of code that follows:

void dispenseChange(double m)
{
	int getMoney();

	//determine the change in coins.. for example 2 dimes, 1 nickel.

	if (getMoney = 1)
		cout << "Your change is $0.75 or 3 quarters.";
	if (getMoney = 2)
		cout << "Your change is $0.50 or 2 quarters.";
	else if (getMoney == 3)
		cout << "Your change is $0.25 or 1 quarter.";
			
}
