App01: Distance Converter

Description

This App allows the user to convert distances measured in one unit of distance into another unit of distance, for example it will convert a distance measured in miles into the same distance measured in feet.

Features Stage 1

The application should:-

1. Output a heading with the name of the application and the name of the programmer.
2. Input any valid distance measured in miles
3. Convert that distance into feet
4. Output the equivalent distance in feet The input and output should accept numbers that include the decimal point, and this app can use the fact that 1.0 miles is exactly 5280 feet.

Features Stage 2

The application should:-

1. Output a heading with the name of the application and the name of the programmer.
2. Input miles and convert it to feet.
3. Input feet and convert it to miles
4. Input miles and convert it to metres This app can use the fact that 1.0 miles contains 1609.34 metres

Features Stage 3

The Application should:

1. Output a heading with the name of the application and the name of the programmer.
2. Prompt the user to select which unit to convert from (Miles, Feet or Metres)
3. Prompt the user to select which unit to convert to (Miles, feet or Metres)
4. Convert the from distance entered into the to distance using the selected units.
5. Output the distance in the to distance units.
6. A Mobile Phone App version of the converter

Design: UML Activity Diagram

Stage 1

Stage 3

Design: UML Class Diagram (10 Marks)

The student should add a Class diagram of the completed App01 here This diagram was created in Visual Studio, but it is a feature that must be added during installation (Visual Studio Page). The relationships (associations) must be added using the toolbox. In doing that it adds more code to your classes. Visual Paradigm is better.

Unit Testing (24 Marks)

This screen shot needs replacing by the students own unit testing

Web App Screen Shots (16 Marks)

A screen shot of the Web App version of the distance converter should be placed here

Evaluation (20 Marks)

The student should add five limitations or useful extensions that could be added to the application

1. When planning my code i would have liked to have included a display menu to navigate through what you would like to convert. instead youre prompted to enter all your conversions at once.
2. Would have also liked to have added a quick feature which would ask the user whether they would like to stick with their conversion unit, switch to a next one or to close the application completely.
