Requirements:
1) Read through Stage 2: Program Development to obtain details of the requirements of this program.
2) Write an algorithm that describes how the program will operate.
a. All program requirements must be included, even if you do not end up including all these requirements in your program code.
b. The algorithm must be structured logically so that the program would function correctly.
3) Prepare and document test cases that can be used to check that the program works correctly,once it has been coded. You do NOT need to actually run the test cases in this stage; this will occur in Stage 3: Testing.
a. All program requirements must be included, even if you do not end up including all these requirements in your program code.
b. Make sure the test cases include checking of data entered by the user to make sure that only valid data is accepted. If the user enters invalid data, the user should be informed of this and given another chance to enter the data. NB: As we have not covered exception handling, you may assume that the user will always enter the expected data type.
c. Test cases should be documented using a template like the one below. You may include extra information if you wish. At this stage, the Actual Result column will be left blank.
