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. Understand basic data types and how operators manipulate data.
  3. Given pseudocode and test data documents, write the C++ code for a program

Exercises

    Answer the following statements as either true or false:

  1. A data type defines a set of values and the set of operations that can be applied on those values.
  2. Reserved or key words can be used as identifier names.
  3. The concept of precedence says that some operators (like multiplication and division) are to be executed before other operators (like addition and subtraction).
  4. An operator that needs two operands, will promote one of the operands as needed to make both operands be of the same data type.
  5. Parentheses change the precedence of operators.

    Answers:

  1. true
  2. false
  3. true
  4. true
  5. false – Parentheses change the order of evaluation in an expression.

Lab assignment

Creating a folder or sub-folder for chapter 03 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_03 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_03_Pseudocode.txt

Download from Connexions: Solution_Lab_03_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_03 and open and study the two files.
  • We have learned that a fundamental concept of interaction with computers is to divide the problem/task into three parts – input, processing and output.  This problem is simple and we will use the IPO (input – processing – output) approach again.  However this time we are going to think about it backwards.  

 

  • What output do I want displayed? 
  • Number of gallons of paint
  • Total cost of the paint

 

  • Thus, what calculations do I need to make?
  • Total cost of the paint is the Number of gallons needed times price per gallon
  • Number of gallons needed is the Total area to be covered (let’s use square feet) divided by the coverage per gallon of paint (Note: you must round up to the next full gallon of paint.)
  • Total area to be covered is the Length times height times 2 added to the width times height times 2

 

  • Which leads us to, what data do I need as input?
  • Price of a gallon of paint
  • Number of square feet that a gallon will cover
  • Length of the house
  • Width of the house
  • Height of the house

 

  • You can see that by working the logic backwards, we can start to completely see what the program must do.  We need to enter some data (input), do some calculations (process) and display the results (output).
  • Copy into your sub-folder: Chapter_03 one of the source code listings that we have used (we suggest the Lab 01 source code) and rename the copy to: Lab_03.cpp
  • Modify the code to follow the Solution_Lab_03_Pseudocode.txt file.
  • I am just going to give you the line of code for rounding up to the next whole gallon of paint (See the “Data Type Conversions” module within Chapter 3 of the Connexions materials. Do you understand why it works?).
  • total_gal_paint = total_area / coverage_gal_paint + 0.9999;
  • 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 03a – instructions

Write the C++ code to do the following pseudocode example.

Pseudocode

Prompt the user for his monthly income. Get the users monthly income.Multiply the monthly income by 12. Display the annual income.Pause the program so the user can see the answer. (HINT: You may call a function.)

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.

what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.

is Bucky paper clear?
CYNTHIA
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.

Do you know which machine is used to that process?

what is the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
Azam
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
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
can nanotechnology change the direction of the face of the world
