You are the owner of a vegetarian pizzeria and you want to write a program to allow the customer to order only ONE pizza online. You will prompt the customer for his/her name, pizza size being order (small, medium, or large), and pizza type being ordered (veggie or cheese), and then input this data. You are to output the customer name, pizza size, pizza type, and cost of pizza back to the customer. For a veggie pizza, small costs $10, medium costs $12.25, and large costs $14.50. For a cheese pizza, small costs $7, medium costs $8, and large costs $9. Be sure to validate the size and type of pizza, and if the data is invalid, output an appropriate message to the customer.
I don't understand how to write this as a pseudocode. This is not my homework. This is an extra problem I'm trying to do on my own to understand how to do other kind of pesudocode's problems.
