Display an order from a nested while loop

LizzleBizzle (2)
Hi all,
Name's Liz, and this is my first post. I've been searching the forums and can't find a thread that answers my question, and I'm kind of stumped.

This is my second program for my CS class, so please bear with me and my lack of experience. I need to design a program that has the following requirements:

"In this assignment you are to write an application for a pizza parlor. The application will allow the user to order 1 or 2 pizzas with 1 or 2 ingredients. The pizzas come in [S]mall, [M]edium, and [L]arge sizes and the list of ingredients include [S]ausage, [P]epperoni, [M]ushroom, [O]nion, [G]reen pepper, [B]lack olive, and [C]anadian bacon.

The costs for the basic pies are $8.95, $9.95 and $10.95 respectively, with each ingredient adding an extra $1.15. Display the order back to them, along with the cost. "

So, if a user ordered two pizzas, one small with pepperoni, and one large with mushroom/black olive, to display the order, it should appear like this:

"Ordered: 1 S (P)
1 L (M, B)
Total cost: $23.35"


I'm having no trouble with the total cost, but I am stumped on how to display the order back to the user because I'm using while loops. Here's my code, and it's messy as heck:

Okay, so I fiddled around with it, and I've altered the part with the ingredients. I don't have the end quite finished, but I'm trying to figure out what to do with my char variables here.

Visual Studio won't let me run my program without first initializing my char variables, orderedIng1 and orderedIng2. Why? And then when I reassign them and output them, they still come up as the initialized values (which are blank spaces). Any tips? Please help.
