B. Lab 5s of 7: Modularization

C. Lab Overview – Scenario / Summary:

TCOs:

TCO: 7

Given a set of program specifications for a simple business problem utilizing a modular design, code and test a program that meets the specifications and employs best programming practices.

TCO: 8

Given a set of program specifications for a simple business problem, code and test a program that implements methods with parameter lists that are passed as supported by the chosen programming language

This lab will familiarize the student with the process of modularizing his or her code.

D. Deliverables:

The Dropbox deliverables include the following.

1. Include a zipped file with all the files from your Visual Basic project (see directions in Doc Sharing on how to collect and zip files.)

2. Create a single MS Word document and include the following.

· For each lab, copy and paste your code directly into the MS Word file.

· Include screenshot(s) of your test data with test results. Enter enough data to demonstrate that all your code has been tested.

· Include another screenshot of the Visual Basic build output messages. Check your build output to make sure you have a successful build with (0) errors and (0) warnings. NOTE: The build output messages appear at the bottom of your window after you click the Build menu and before you click the Start Without Debugging option. Your build output messages provide a list of compiler warnings or errors and let you know whether your program compiled successfully.

· Include the Word document as part of the zipped project file.

3. Upload each part of the lab into its corresponding weekly Dropbox.

E. Lab Steps:

Preparation:

If you are using the Citrix remote lab, follow the login instructions located in the iLab tab in Course Home.

string input procedure as read only

For the validate number input function, the description of

the type of information that is being validated, the actual

string input, and both the minimum and maximum values

need to be passed into the procedure by value. The actual

data value parameter will need to be passed in by

reference since it will be changed by the procedure.

The seasons goals and assists are passed in

by value to the AddTotals function, which

then returns the points for that season

DisplayRunningTotals(count, goals, assists,

point)

The season count, goals, assists, and points

are passed in by value and the procedure

then sets the values in the output list

Start

The collect statistics procedure prompts the

user for the goals and assists for each season,

calculates the season points, and then

displays the running totals in the list box.

All data variables can be declared locally, and

there is no need to pass in any data to the

Collect Statistics procedure.

Start

By value dataDescription

By value Min value

By value Max value

The Get Data function prompts the user

for the type of data that is being

collected, and then uses the Validate

Number function to validate the

provided value.

The description of the type of

information that is being collected and

the minimum and maximum values need

to be passed into the procedure by

value. The value will then be returned by

the function

Response = InputBox(“Enter the number of “

& dataDescription & “ between “ & min & “

and & “max”

Validate Number

Input(dataDescription, response,

min, max, value)

The Validate Number Input

function is being re-used, and in

this case you pass in the

arguments of the Get Data

function along with locally

declared response and value

variables into the Validate

Number Input function

min <= value <=

The display running totals procedure

adds the season data to the list box.

need to be passed in by value.

The reason you put this into a separate

module is that if you want to change the

output control then you have localized
