TGI Today

After I take attendance, I'll answer any questions you have about operators. I'll then post the quiz, as promised.

After you finish the quiz, you'll have the rest of the class to work on the coin program.

After your program is complete, be sure to upload main.cpp from the coin project using both your and your partner's last name.

Pizza Continued. DunDunDuuuun...

First, we're going to be finishing the program from yesterday. Good fun.

Then we're going to learn about operators. [note- no at&t employees will be harmed during this lesson]

Pepperoni Pie in Your Eye

Goal #1: I want you to transfer all your msvc++ projects to your flashdisk. That means remove them from "My Documents" and onto your flashdisk. Subsequent projects will all be saved there.

Goal #2: Learn the super-useful "if" statement.

Goal #3: We're going to write a program which could be used by a pizza joint to total up a customer's order. The program must have at least 7 menu items with prices. The user must be able to add multiple items to the customer's order. At the end of the order, the program should show the total cost (with the associated 5.5% sales tax [dine-in obviously]). After that customer's order is totaled, the program should repeat so that more orders can be taken for new customers. We'll write the pseudocode for this program together. This is due at the end of class tomorrow.

if (Good Day == Guten Tag) {you = german;}

Last week, we wrote our first program, hello world.

We're going to pick up right where we left off. Go ahead and get msvc++ fired up and start a new project.

Today's task is to write a program which prompts the user for a radius and calculates circumference, area, and volume for circular shapes.
