## Learning Objectives

With 100% accuracy during a: memory building activity, exercises, lab assignment, problems, or timed quiz/exam; the student is expected to:

Define the terms on the definitions as listed in the modules associated with this chapter.

Given a testing shell program already coded and tested, create a user defined specific task header file, a user defined specific task prototypes document and a source code program to verify that the header file works properly.

## Exercises

Questions
1. Scope refers to a brand of mouth wash.
2. User defined specific task functions are usually placed into a user defined library.
3. Local and global data storage is associated with the concept of scope.
5. The stack is part of the computer’s memory used for storage of data.
1. False–Although Scope is a brand of mouth wash; we are looking for the computer related definition.
2. True
3. True
4. False-it may seem difficult at first, but with a little practice it is really quite easy.
5. True


## Lab Assignment

#### Creating a Folder or Sub-Folder for Chapter 07 Files

Depending on your compiler/IDE, you should decide where to download and store source code files for processing. Prudence dictates that you create these folders as needed prior to downloading source code files. A suggested sub-folder for the Bloodshed Dev-C++ 5 compiler/IDE might be named:

• Chapter_07 within the folder named: Cpp_Source_Code_Files

If you have not done so, please create the folder(s) and/or sub-folder(s) as appropriate.

Download and store the following file(s) to your storage device in the appropriate folder(s). You may need to right click on the link and select "Save Target As" in order to download the file.

#### Detailed Lab Instructions

Read and follow the directions below carefully, and perform the steps in the order listed.

• Navigate to your sub-folder: Chapter_07. Compile and run the Lab 07 Testing Shell source code. Note: This program uses an include file that points to the "udst_monitor.h" file as explained in Connexions Chapter 7 materials.
• Following same process as shown in the Connexions module "Using a Header File for User Defined Specific Task Functions" that is within the Chapter 7 materials; make the following files: udst_us_to_metric.h and udst_us_to_metric_prototypes.txt and Lab_07_Verify_Header.cpp
• After you have successfully written this program, if you are taking this course for college credit, follow the instructions from your professor/instructor for submitting it for grading.

## Problems

#### Problem 07a - Instructions

Create the pseudocode to solve the following specific task function:

Problem: An interior designer always needs to calculate the area of a room to determine the amount of floor covering needed (usually carpet). The rooms are rectangular with the dimensions measured in feet (with decimal fractions). The function however needs to return square yards. Hint: There are 3 lineal feet to a yard.

#### Problem 07b - Instructions

Create test data for the following specific task function:

Problem: An interior designer always needs to calculate the area of a room to determine the amount of floor covering needed (usually carpet). The rooms are rectangular with the dimensions measured in feet (with decimal fractions). The function however needs to return square yards. Hint: There are 3 lineal feet to a yard.
