Lab assignment

Creating a folder or sub-folder for chapter 04 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_04 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.

Detailed lab instructions

Read and follow the directions below carefully, and perform the steps in the order listed.

  • The Problem/Task – I have a friend who is visiting from Europe and he does not understand Fahrenheit temperatures.  We need to write a program that allows him to enter the temperature in Fahrenheit (as announced on TV or radio) and convert it to Celsius.  Clue 1:  Fahrenheit water freezes at 32 degrees and boils at 212 degrees.  Celsius water freezes a zero (0) degrees and boils at 100 degrees.  Google the internet (how to convert Fahrenheit to Celsius) if you need more help.  Clue 2: You can also use Internet sites to do a conversion and thus create your test data.
  • You only need two variables in this program: Fahrenheit and Celsius both of which should be the integer data type. When you convert the Fahrenheit to Celsius you will need to use a floating-point expression doing floating-point calculations for precision. Additionally we want to round up or down the Celsius answer by adding 0.5 to the calculation expression.
  • Within your sub-folder: Chapter_04 you will need to create three files: Lab_04_Pseudocode.txt and Lab_04_Test_Data.txt and Lab_04.cpp NOTE: It will be easier to copy some previous files from another assignment and use those copies by renaming them and modifying them as appropriate. The professor is expecting the items you create to have a similar format to those we have been using in the course.
  • Create your pseudocode, test data and source code files.
  • Build (compile and run) your program. You have successfully written this program when it runs with your test data and gives the predicted results.
  • 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 04a – instructions

Decide on the data type and identifier names for the following:

Problem: A men's clothing store that caters to the very rich wants to create a data base for its customers that records clothing measurements. They need to record information for shoes, socks, pants, dress shirts and casual shirts. HINT: You may need more than 5 data items.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

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.
