Lab assignment
Creating a folder or sub-folder for chapter 17 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_17 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.

Detailed lab instructions
Read and follow the directions below carefully, and perform the steps in the order listed.
- Compile and run the Lab_17a.cpp source code file. Understand how it works.
- Copy the source code file Lab_17a.cpp naming it: Lab_17b.cpp
- Convert the code that is using the if then else to a conditional expression.
- Convert the code that is using the conditional expression to an if then else.
- 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.
