I am doing COMP200 at Athabasca and our 2nd project is with GoodDocsF.cpp (This is meant to be an introductory course with no prerequisites) I know enough HTML and JavaScript to be dangerous but I have no C++ at all.

I have my files all installed and I'm comfortable using the cmd prompt. I think the question being asked is for us to put a temperature into the code in Farenheight or Celcius using F or C but where you put it into the code or why I have no idea.

cout<<"Whatistheinputtemperature?";

cin>>input_temp; DO I put 32F here? if so is that the right format? Should I be using brackets?

Have I completely misunderstood what is going on?

Title: GoodDocsF.cpp

Description: Temperature Conversion Program

Date: December 8, 2013

DOCUMENTATION

Program Purpose:

Demonstrate proper format for documentation, test plans and comments.

Also demonstrate user prompts, keyboard input, simple calculations and output,

specifically converting temperatures from F to C.

Compile (assuming mingw compiler and opened command prompt): g++ -o GoodDocsF GoodDocsF.cpp

Execution (in a Command Prompt window): GoodDocsF.exe (or just GoodDocsF)

Classes: none

Variables:

input_units (char) = C or F to designate temperature units for the supplied input temperature.

output_units (char) = C or F to designate temperature units desired for the output conversion,

input_temp (float) = real (decimal) number supplied by user which is the input temperature.

output_temp (float) = calculated output temperature in output_units as a real (decimal) number.

Formulae:

The formula for converting temperatures from Fahrenheit to Celcius is:

T(C) = (T(F) - 32.0) * 5.0 / 9.0;

The formula for converting temperatures from Celcius to Fahrenheit is:

T(F) = (T(C) * 9.0 / 5.0) + 32.0

It is important to use decimal numbers especially in the division to avoid integer devision.

It is also important use use the parenthesis to enforce calculation order.

TEST PLAN

Normal case 1:

>What is the input temperature? 32

>What are the units of the input temperature (C for Celcius or F for Fahrenheit)? F

>Your input temperature is 32F which is 0C.

Normal case 2:

>What is the input temperature? 100

>What are the units of the input temperature (C for Celcius or F for Fahrenheit)? C

>Your input temperature is 100C which is 212F.

Bad Data case 1 (temperature out of range):

>What is the input temperature? -4000

>What are the units of the input temperature (C for Celcius or F for Fahrenheit)? C

>Your input temperature is -4000C which is out of range (less than -273.15C or -416F)..

Bad Data case 2 (incorrect units):

>What is the input temperature? -40

>What are the units of the input temperature (C for Celcius or F for Fahrenheit)? Q

>The units you have specified are not one of C (Celcius) or F (Fahrenheit).

Discussion:

The program accepts any integer or decimal input temperature and a unit character which must be either C, c, F or f.

The program then prints the input temperature as well as the temperature converted into the non-input units.

Temperature range is from -273C (-415F) to any positive number.
