    Lab Assignment

    Creating a Folder or Sub-Folder for Chapter 16 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_16 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_16_Pseudocode.txt
