    Questions
        1. Most programmers rarely worry about efficiency.
        2. Modular/structured programming helps improve efficiency.
        3. Flexible coding helps improve efficiency.
        4. Who cares about indentation and alignment within source code. It's a waste of time.
        5. Versatile code is a concept that is easy to understand.
    Answers    
        1. False - Efficiency of code execution, no; efficiency of code production and maintenance, yes.
        2. True
        3. True
        4. False
        5. Maybe true and maybe false - It does require some effort to catch on to how it works.
    

    Lab Assignment

    Creating a Folder or Sub-Folder for Chapter 21 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_21 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.
