## Lab Assignment

#### Creating a Folder or Sub-Folder for Chapter 11 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_11 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.

• Create a source code file from the Lab_11_Pseudocode.txt file. Name it: Lab_11.cpp
• Build (compile and run) your program.
• 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 11a - Instructions

Create a table with the six relational operators and their meanings.

#### Problem 11b - Instructions

Explain why we are using the "if then else" to manipulate the input data in the example below.

C++ Source Code
cout << "\nEnter one side of the rectangle --------->: " ;
cin >> side1;
cout << "\nEnter the other side of the rectangle --->: " ;
cin >> side2;

if (side1 > side2)
{
length = side1;
width = side2;
}
else
{
length = side2;
width = side1;
}
