TCO 3: Given a simple problem, design and desk-check a solution algorithm requiring a modular

design that is expressed in terms of pseudocode or program notes, input-process-output (IPO) analysis,

and flow chart.

TCO 7: Given a program with logic errors that is intended as a solution to a simple problem, employ

debugging diagnostics to remove and correct the errors.

TCO 8: Given a more complex problem, develop a complete solution that includes a comprehensive

statement of the problem, complete program design, and program documentation.

Scenario

Your algorithm will write two functions called ComputeTotal( ) and ComputeTax( ).

ComputeTotal( ) will receive the quantity of items purchased, and the unit price of each item.

It will return the total sales (quantity times price).

ComputeTax( ) will receive total sales as a number and the state as a string and return the

amount of tax depending on the state. NJ requires 7% tax, FL requires 6% tax, and NY

has 4% tax.

The main program will ask for the name of the customer and read the name in a variable

called name. It will also ask for one of the three states listed above. It will ask for the number

of items sold and the unit price of the item.

Main will then call ComputeTotal( ), passing the quantity and unit price. Main will then call

ComputeTax( ), passing the state and the amount of sales and receive back the tax. Finally

Main( ) will print out the total sales, the tax amount, and the total with taxes. For example, see

below.

Enter the name of the customer: Jack

In which state (NY / NJ / FL) ? NJ

How many items were purchased?: 3

What was the unit price of the items?: 1.50

The total sales for Jack are \$4.50

The total with taxes is \$4.82

Make sure you save the return values into an appropriate variable. Use formatted

output to make the program more user friendly.

Be sure to think about the logic and design first (IPO chart, pseudocode, and flowchart), then

code the C# program. Rubric Point distribution for this activity:
