Need help (im bad with classes)

[xIamAxel]

Okay so I made this program that takes 2 numbers(the price of the item and the money you pay with) and its turns everything into mininmun amout of change. Ex Item cost 49.99 I pay with 53 (for some reason) it gives back 2 dollars 3 quarters 2 dimes and 4 pennies (not sure if thats right but you get the point). Now the problem Im having is making everything i have into classes(or object oriented programming or whatever). I started but im stuck and could use any kind of help.
TL:DR I have one .cpp file that needs to be simplified with classes

Original

#include <iostream>

using namespace std;



int main()

	int Five_Bill = 0;

	int Penny = 0;
