Question 1.

Write a program that prompts the user for a positive integer greater than 1. The program should then output either "prime" if the given number is a prime or "composite" otherwise. Recall that an integer is prime if and only if its only divisors are 1 and itself.

Question 2.

1. Your program should simulate a checkout counter.  It should work like the following example:

<Program> Welcome to the checkout counter!  How many items are you purchasing today?

<User> 3 (user presses Enter key)

<Program> Please enter the name of product 1:

<User> chicken (user presses Enter key)

<Program> And how much does chicken cost?  

<User> 3.50 (user presses Enter key)

<Program> Please enter the name of product 2:  

<User> chips (user presses Enter key)

<Program> And how much does chips cost?  

<User> 1.25 (user presses Enter key)

<Program> Please enter the name of product 3: 

<User> gum (user presses Enter key)

<Program> And how much does gum cost?

<User> .99 (user presses Enter key)

<Program>

Your order was:

chicken $3.50

chips $1.25

gum $.99

Your subtotal comes to $5.74.  With 9% sales tax, your total is $6.19.

Please enter cash amount:

<User> 20.00 (user presses Enter key)

<Program>

I owe you back $13.81.
