/* Cash Register Counter This C++ code is a simple program for calculating the total amount of a cash register, a specially when you need to count the momey manually. After counting one of the money types, enter that amount and count the next type of money. If all done, then this program can show an overview with the amounts of money types, the total of every money type and the total of money in the entire cash register. Example: TOTAL IN CASH REGISTER: Money type Amoumt Total 50.00 x 0.00 = 0.00 20.00 x 6.00 = 120.00 10.00 x 7.00 = 70.00 5.00 x 0.00 = 0.00 2.00 x 33.00 = 66.00 1.00 x 56.00 = 56.00 0.50 x 42.00 = 21.00 0.20 x 67.00 = 13.40 0.10 x 77.00 = 7.70 0.05 x 33.00 = 1.65 0.02 x 0.00 = 0.00 0.01 x 0.00 = 0.00 Total in Cash Register: 355.75 The best way to see the code working is to run it on a system with a console environment.
