Assignment: Software Design and Modeling
Outcomes addressed in this activity:
Unit Outcomes:
- Differentiate between various software development methodologies.
- Select an appropriate methodology for a particular software development project.
- Examine software design and modeling techniques.
- Apply software design tools.
Course Outcomes practiced in this unit:
1: Implement various software process models.
2: Apply critical thinking to formulate a logical solution to a problem.
Purpose
Given a requirement, you will examine various software design and modeling techniques by diagramming and analyzing a solution. You will create an IPO chart, pseudo-code, flowchart diagram and perform a desk-check analysis to help formulate your solution to the problem posed.
Assignment Instructions
Note: For this assignment, you will not be writing any actual code. You are just going through the design and modeling of this scenario.
Using an IPO chart, a flowchart diagram, and pseudocode, you will design a routine that will accept a Fahrenheit temperature and convert that temperature to its Celsius and Kelvin equivalents. Hint: The term routine can mean function, subroutine, procedure, etc., depending on the language in question.
Assignment Requirements
A user enters in a Fahrenheit temperature, and gets back two values:
- Celsius temperature
- Kelvin temperature
The code routine will accept one argument, tempFahrenheit and will calculate two values, tempCelsius and tempKelvin.
It will call two routines internally:
- ConvertFahrenheitToCelsius will be a routine to convert a Fahrenheit temperature to Celsius
- ConvertFahrenheitToKelvin will be a routine to convert a Fahrenheit temperature to Kelvin.
Use these variable and routine names in your solution.
Research and find the formulas to convert Fahrenheit temperature to Celsius and Kelvin and then apply critical thinking skills to formulate a logical programmatic solution to convert the user-entered value of Fahrenheit temperature to Celsius and Kelvin equivalents.
Then design the two routines that will implement the formulas you found in your research.
We do this by examining how the routines should behave and walk ourselves through the design using the following tools.
- Create your IPO chart. This is where you determine your inputs-processes-outputs.
- Create a flowchart diagram showing the flow of logic for the solution to these problems.
- Create your pseudo-code. Hint: Pseudocode is a mix of simple syntax from real programming languages and English. When modeling your full routine or program you will show every aspect of it in the pseudocode. In the case of adding your algorithms or processing to IPO charts or flowcharts, you can use snippets of the pseudocode to only show the pertinent processing.
