Question

Assignment 2: Restaurant Choices

Please include source code.

Write a program that allows a user to choose as many sides for a meal as they want (it’s an ‘all you can eat’ special!).

1. Print out a menu and let the user choose a side on the menu. 2. Use a switch statement to print out the side chosen.

3. After printing the side, loop back to let the user enter another side.

4.Make sure that if the user types in a number not on the menu

that the program prints out an error message and loops back to allow the user to re-type the choice.

5.Put a 'quit' in the menu to allow the user to quit choosing sides.

Requirements:

Use a switch statement and a loop statement (for, while or do/while) in your code.

If you need to use a string (not necessary for this exercise), use C strings. No 'string' type allowed.
