Week 1 iLab

------------------------------------------------- TCO 1: Given a simple problem, design and desk-check a solution that is expressed in terms of pseudocode, flowchart, and/or input-process-output (IPO) diagrams. iLab This exercise will cover the steps used to create a solution. You will use variable lists, IPO charts, pseudocode, flowcharts, and desk-checking. Rubric

Problem

You have an idea for a restaurant tip calculator app that you want to develop for use on your mobile phone when you go out to eat. You can enter the amount of the check before taxes, the tax rate, and the tip percentage. It should display the amount before taxes, the dollar amount of the taxes, the dollar amount of the tip (calculated on amount before taxes), and the total amount including taxes and tip.

(1) Variable List With Data Type
List all the variables you will use (use valid variable names). Indicate whether the data type is string, integer, or decimal, and so on.
Check Amount double
Tax Rate double
Tip Percent double
Tax Amount double
Tip Amount double
Grand Total double

(2) IPO Model
List the inputs, any processes, calculations, and outputs. Use the same valid variable names you used in Step 1.

Inputs | Process (calculations) | Outputs | check AmounttaxRatetipPercent | taxAmount = checkAmount * taxRatetipAmount = checkAmount * tipPercentgrandTotal = checkAmount + taxAmount + tipAmount | check AmounttaxAmounttipAmountgrandTotal |
