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. Identify which selection control structures are two-way selection and which are multiway selection.
  3. Understand, define and/or explain case, switch and nested if then else.
  4. Be able to write pseudo code or flowcharting for the case control structure.
  5. Be able to write C++ source code for a case structure using equality and listed values (switch with break to act like a case structure).
  6. Be able to write C++ source code for a case structure using ranges of values or floating-point values (nested if then else to act like a case structure).
  7. When feasible, be able to convert C++ source code from switch acting like a case to nested if then else and vice versa.

Lab assignment

Creating a folder or sub-folder for chapter 12 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_12 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_12a.cpp

Detailed lab instructions

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

  • Compile and run the Lab_12a.cpp source code file. Understand how it works.
  • Copy the source code file Lab_12a.cpp naming it: Lab_12b.cpp
  • Convert the nested if then else to a switch with breaks.
  • 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.

Problem 12a – instructions

Flowchart the following pseudocode:

Problem 12b – instructions

The "Flip-Flops" is a unique shoe store that only sells flip-flops. Adult shoe sizes less than 4 are handled in the children’s department, thus we don’t need to concern ourselves with sizes less than 4. Half shoe sizes are to be rounded down, thus the prompt to the user that happens before this case structure will have addressed that issue. The variable shoe_size will be an integer value between 4 and 1,000,000,000 (one billion).

Write C++ source code for the following pseudocode:

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?
ninjadapaul
hmm
Abhi
is it a question of log
Abhi
🤔.

or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

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?

not now but maybe in future only AgNP maybe any other nanomaterials

this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15

can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
