  2. * Group project: Food ordering system
  3. * STIA1113: PROGRAMMING I
  4. *
  5. * Group members:
  6. * 1.Ibtihal Hasmad (274790)
  7. * 2.Rian Rashad Abdo Saeed AlAreqi (268922)
  8. *
  9. * Date last midified: 24/1/2020
  10. * description of the project:
  11. *
  12. *The Restaurant needs a program that helps students choosing their meals easily.
  13. The program will ask the user to input: Name,the choice of meal,
  14. additional meals if they like to add,and if they want to continue with the order.
  15. The data of the customer/customers will be stored within the program
  16. and there is 3% tax that will be charged from the customer automatically.
  17. Creating this application, will reduce reason for students to skip the meals,
  18. help them to avoid consuming ingredients that they are allergic to,
  19. part time for students who want to work for delivery foods, and also saving their times.
  20. ***************************
  21. *
  22. * User Guide:
  23. * 1.Choose one of the restaurants 1-3
  24. * 2.Choose your meal from the menu.
  25. * 3.If you want another meal type (yes).
  26. * 4.Enter your name.
  27. * 5.choose payment methods,pay by cash or by online banking.
