Variable and Algorithm Lab

Overview

Write your first Miracle algorithm demonstrating your mastery of variable input, output, and conversion. The important part of the program is the algorithm, although you will test it by implementing it in the Miracle environment.

The Program

Write a program that asks the user his or her name. It then asks for two numeric values. It returns the sum, difference, product, and quotient of these two variables. The program then thanks the user for playing by name. Here's a sample run (computer output in bold):

Welcome to the calculator!
What is your name? Andy
Nice to meet you, Andy!
Please enter a number 8
Please enter another number 4
8 + 4 = 12
8-4 = 4
8 * 4 = 24
8 / 4 = 2
Thanks for playing, Andy! 

Deliverables

The purpose of this assignment is to create an algorithm. A working program is a great way to test that your algorithm is correct, but it's not really the main point of the exercise. A good project will have these characteristics:

• The STAIR process for this program outlined as done in class for this type of problem. (eg list all the tools, shake them into the right order, flesh out each command with the appropriate sentence)
• Turn in your algorithm in Word format to the drop box
• Incorporate a code trace (also in your Word document) as a test of the algorithm.
• Test again using Miracle
• Once you have working Miracle code, copy that into your Word document as well.
• The Miracle program won't look like the test-based listing above, because it uses dialog boxes for input and output. That's not a problem.
• Do these basics, but once you've done that, feel free to spruce up your code in other ways (maybe investigate other math functions or something.)
