We are going to use psuedocode to code an application used to purchase pizza. This program will assess your ability to

get input and print output, use loops and decision structures, and perform basic calculations. $($The exam covers Chapters

$1-4).$ Please ensure you include your IPO chart.

To start, display a welcome message: Welcome to Pizza Planet!

You will prompt the user to enter their name.

You will then ask the user how many pizzas they would like to order $(1-10)$

A while loop will be used, to validate the number of pizzas is between $1-10.$ If the user inputs a number less than zero or

greater than $10$ the following error message will display.

Invalid Input. You must order between $1$ and $10$ pizzas

Once you get a valid number for the number of pizzas ordered you will continue with the program

Let the user know if they purchase four or more pizzas, they will receive a $15\%$ discount on their total order.

If you order $4$ or more pizzas, you'll receive a discount of $15\%.$

Assume the pizza sizes are the same for everyone.

Menu shown below:

Enter C for Cheese

Enter P for Pepperoni

Enter S for Supreme

Enter V for Veggie

With a while loop, validate the pizza codes to ensure that they are either C$,$ P$,$ S$,$ or V$.$ If they choose any other option

than C$,$ P$,$ S$,$ or V display a message like the one below and allow them to input the pizza choices again:
