Exercises

    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.

    Answers:

  1. false

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.

Download from Connexions: Solution_Lab_01.cpp

Download from Connexions: Solution_Lab_01_Pseudocode.txt

Download from Connexions: Solution_Lab_01_Test_Data.txt

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.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
