• Cafeteria-POO is a cafeteria system that I made for the OOP course at college (and that's why the software content is in Portuguese).
• When you open the software, it already presents you with the purchase menu, where you choose which ingredients go in your sandwich, while at the same time it updates the total price of the order.
• When confirming the order, a screen opens with proof of purchase.
• It is also possible to see all requests made in that section (data persistence was not done, but all abstraction is already done for a future implementation)
