Your assignment is to write a pizza ordering system for the mighty Pizza Yurt chain. You must implement the program using separate functions for each major component of the program. In addition, we will continue using lots of loops and tests.
Your final program should do the following:
An important part of this assignment is breaking down the problem into smaller steps and writing a function for each step. Here are examples of possible functions you may want to write:
get_num_pizzaschecks to make sure valid number is entered, returns int.
get_pizza_sizechecks to make sure valid letter is entered, returns char.
print_ordershows total small, medium, and large pizzas and total toppings.
print_receiptcalculates cost of all items, subtotal, tax, and total.
calc_taxdetermines the tax given a double and returns a double.
Here is a sample run of the program. The user's input is shown in bold:
