Lab assignment

Creating a folder or sub-folder for chapter 22 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_22 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 the lab file(s)

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.

Download from Connexions: Lab_22_Pseudocode.txt

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_22_Pseudocode.txt file. Name it: Lab_22.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 22a – instructions
