Learning objectives

With 100% accuracy during a: memory building activity, exercises, lab assignment, problems, or timed quiz/exam; the student is expected to:

  1. Define the terms on the definitions as listed in the modules associated with this chapter.
  2. Given pseudocode, test data and source code of an existing program, modify the pseudocode and source code to create "program control" functions.

Memory building activities

    Answer the following statements as either true or false:

  1. Pseudocode has a strict set of rules and is the same everywhere in the computer programming industry.
  2. Hierarchy Charts and Structure Charts are basically the same thing.
  3. Program Control functions are used to simply sub divide and control the program.
  4. The void data type is rarely used in C++.
  5. Making source code readable is only used by beginning programmers.

Lab assignment

Creating a folder or sub-folder for chapter 06 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_06 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.

  • Navigate to your sub-folder: Chapter_06. Review the original Lab 01 materials. Compile and run the Lab 01 source code. Then review and compare the original Lab 01 materials to modularized Lab 01 materials taking note of the conversion to "program control" functions. Compile and run the Lab 01m source code. Review as needed the course materials. Email your professor if you have any questions.
  • We have supplied the solution to the Lab 03 assignment. Review the Lab 03 assignment by compiling and running the Lab 03 source code.
  • You need to copy the Lab 03 source code file and pseudocode file to make the following new files: Lab_06.cpp and Lab_06_Pseudocode.txt
  • Modify the Lab 06 pseudocode file to implement “program control” functions as shown in the demonstration materials.
  • Modify the Lab 06 source code file to implement “program control” functions as shown in the demonstration materials.
  • Build (compile and run) your program. You have successfully written this program if when it runs and you use the test data [use the same test data as used in Lab 03] it gives the same results as Lab 03.
  • 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.

please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
yes that's correct
