C++ Assignment 12
Snack Bar program and strings

Your assignment is to write a program that will function as a point-of-sale-system at a snack bar. The snack bar sells only five different items: a sandwich, chips, pickle, brownie, and soda. All items are subject to San Francisco sales tax of 8.25%. You should choose the sale prices of the products.

The program should repeatedly display the menu below until the sale is totaled. The program should keep a running total of the amount of the sale based on costs that you place in constants for each of the food items. The running total should be displayed somewhere on the screen each time the menu is displayed again. If the sale is canceled, clear your running total and display the menu again. When the sale is totaled, calculate the sales tax and print the final total due on the screen along with a "Thank You for Your Order" message and a random order number.

Program Requirements

• Use C++ strings: #include <string>
• Be fully modular: use appropriate functions with pass by value arguments--do not use global variables.
• Include the following functions in addition to main()
  1. void SetTwoDecimalPlaces (); //click on the link to download
  2. void CurrentOrder (int nSandwiches, int nChips, int nPickles, int nBrownies, int nSodas);
  3. void Introduction();
  4. void Conclusion(int nSandwiches, int nChips, int nPickles, int nBrownies, int nSodas);
• Use 5 local variables in main() to keep track of the number of items in the current order.
• Use a loop in main() to take orders
• Pass the order from main() to the CurrentOrder() function that calculates and displays the current costs.
• Use global constants for the price of each item and sales tax. Use Hungarian notation (caps) for the constant names.
• Use the tab character '\t' to "line up" the dollar values (Note: Backslash \ and forward slash / are NOT the same! )
• Include sample output
• Use system("CLS"); to clear the screen every time it is updated
• Display an appropriate message if the user asks for an item that is not on the menu
• Use all the elements of good style that we have learned so far
