Assignment Brief Scenario: Please refer to scenario in Assignment 1. Tasks 1 Your next task is to implement the software that you designed in previous steps. You need to implement the software designed in assignment 1 using C programming language. Your code must make use of programming standards, including file headers and effective code commenting. You need to provide screenshots of your program when running. During the development of your program, if you make any changes to the original design, state them with reasons in report. Your code listings must be included as an appendix. Task 2 Test your program by making a test plan, execute it and log results. Your test plan should include data validation and program operations based on requirements. Test results (passed or failed) should be analysed to help the program in future maintenance. Task 3 Write an evaluation and conclusion of the whole development. The evaluation of your program should be based on its running and its test result. You should mention about lessons learnt and future improvement. Also evaluate how procedural programming is applied in your program, state benefits, disadvantages or difficulties. A final report of these 3 tasks must be submitted in PDF format to CMS. Submission Format The submission is in the form of a Word document. You are required to make use of appropriate structure, including headings, paragraphs, subsections and illustrations as appropriate, and all work must be supported with research and referenced using the Harvard referencing system.

- Input student ID and check if the ID is duplicated or not. If it is duplicated, the user needs to input it again.
- Input student Grade and check if the grade is valid or not. If it is not valid, the user needs to input it again.
- Function output information of students: Help you print student information to the screen.
- Function find the maximum grade of student: Help you find the student who has maximum grades and print to the screen.
- max = Grade[0]
- If max < Grade[i] then max = Grade[i]
- Print the result on the screen.
- Function find the minimum grade student: Help you find the student who has minimum grades and print to the screen.
- min = Grade[0]
- If min > Grade[i] then min = Grade[i]
- Print the result on the screen. The screenshot:
- Function input information of students:
- Function find the minimum grade student:
- When Enter choice: 3
- Function exit menu:
- When Enter choice: 4 3. Change from the original designed:
- āswitchā¦caseā statement to āifā¦elseā: The if else statement is a conditional statement that will run a set of statements depending on whether the condition is true or false. Switches can be used to test a single variable. The difference between if else and switch is that the if else block executes based on the evaluation of the expression in the if statement, while the switch statement selects the statements to execute depending on the single variable, passed to it. Shorter structure than "switch...case".
- Declare more variable c: So that when entering "Enter number of student" as a character, the program will report an error and force re-enter a larger number.
II. Test the program with proper test plan.

- Verify that Student information will save into array if user enters valid information. InputStudent - Enter number of student: 2
- Enter student ID 1: 3
- Enter student Grade 1: 8
- Enter student ID 2: 5
- Enter student Grade 2: 9
- ID[] = {3,5}
- ID[] = {3,5}
- Verify that "Invalid student number, please enter again" when the user enters the negative number.
- Enter number of student: - 2 Display information: āInvalid number of students, please enter again ā Display information: āInvalid number of students, please enter again ā Pass
- Verify that "Invalid student number, please enter again" when the user
- Enter number of student: āaā Display information: āInvalid number of students, please enter again ā Display information: āInvalid number of students, please enter again ā Pass
user selects "Maximum grade of student".
- Enter student ID 2: 5
- Enter student Grade 2: 9
- Enter choice: 2
- Verify that "Student Minimum Score" is displayed when the user selects "Minimum grade of student". FindMin - Enter number of student: 2
- Enter student ID 1: 3
- Enter student Grade 1: 8
- Enter student ID 2: 5
- Enter student Grade 2: 9
- Enter choice: 3 Minimum grade of student 8. 00 Minimum grade of student 8. 00 Pass
- Verify that ā Please input againā when the user enters the value larger than 10. InputStudent - Enter number of student:
- Enter student ID 1:
- Enter student Grade 1: Display information: āPlease Input againā Display information: āPlease Input againā Pass
- Verify that ā Please input againā when the user enters the value smaller than
- Enter number of student:
- Enter student ID 1:
- Enter student Grade 1:- 3 Display information: āPlease Input againā Display information: āPlease Input againā Pass
III. Analyse test results for future maintence.
IV. Evaluate your program, state lessons learnt and future inprovement.
