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
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_16_Pseudocode.txt file. Name it: Lab_16.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 16a - Instructions
Describe the normal C++ operators allowed with the string data type.
Problem 16b - Instructions
Describe why unary positive is worthless.
Problem 16c - Instructions
Describe how unary negative works.
