Мне нужно написать программу для ресторана. Используя C. Нужно добавить некоторые элементы
Question : Write a program for a restaurant. Your program should display a main menu that allows the customer to select between the breakfast menu option,lunch menu option, dinner menu option and check out option. After selected an option from the main menu, your program should continue to display a sub-menu that will show the available foods and prices for the selected meal.Your program should allow the customer to select the food and enter the order quantity. Your program should continue to allow the customer to order their food until they select the check out option in the main menu,then only your program will display the order list with the quantity, prices and total amount need to pay by the customer.
Это моя кодировка , и мне нужно улучшить ее, чтобы отобразить квитанцию о приобретенных товарах, общую сумму, которую нужно оплатить, и позволить пользователю ввести денежную сумму, которую он собирается заплатить, и рассчитать баланс для них. Пожалуйста, помогите мне.

Какая часть дает вам трудности?
Что вы пробовали, и где вы застряли?
Я знаю, что вы хотите "улучшить его, чтобы отобразить квитанцию о приобретенных товарах..." и так далее, но я не знаю, почему это создает вам проблему!

Я застрял в той части, где не мог рассчитать общую сумму. Как я могу применить его к программе. Я немного запутался в этом

используйте еще несколько подпрограмм для очистки кода. И некоторые константы или определения.
Это часто помогает яснее видеть, что делать в такой неразберихе ;-)
