▪ Function input information of students: Helps you check if you have entered the recently entered ID, use for loop to check in the array ID. ▪ Input student’s ID and check if the ID is duplicated or not. If it is duplicated, the user need to input again. ▪ Input student’s grades and check if the grades is valid or not. If it is not valid, the user need to input again. Figure 2 : Input information of student. ▪ Function display information of student: Helps you print information of student to the screen.
Figure 3 : Print information of student to the screen. ▪ Function find highest grades of student: Helps you find the student has highest grades and print to the screen, ▪ Max=grades[0], max ID=IDs[0]. ▪ I from 0 to students - 1. ▪ If max < grades[i] then max=grades[i], max ID=IDs[i]. ▪ Prints the result on the screen.

▪ Menu Options:
Figure 8 : Menu Options.
- The user will be forced to enter a number from 1 and 5 to execute the option. If the userenters a number other less 1 or than 5, the programs will require input again.
▪ Display information of the students to the screen:
Figure 10 : Display information of the students.
- After inputting student’s grades and IDs, we will print the list of student information.
▪ Find the highest grades of student:
Figure 11 : Find the highest grades of student.
- The students who have the highest grades will be identified after the program prints the highest grade list, which includes the grades and IDs of the people who have the highest grades.
▪ Find the lowest grades of student:
Figure 12 : Find the lowest grades of student.
- The students who have the lowest grades will be identified after the program prints the lowest grade list, which includes the grades and IDs of the people who have the lowestgrades.
▪ Exit program:
Figure 13 : Exit program.
- The screen will display “Exiting program …” and a way to close the program (cmd). III. Testing
1. Test plan
Before going in the work, a test plan should be made base on the requirements of the problem given. The test plan will come with the measure for achievements:
Input student grades Float grades Try to input boundary data, typical data, bad data A,b.c.*,& Error Accepted Typical data (1,2,3..) Accepted Accepted Pass Decimal in typical data(1.1,1.2…) Accepted Accepted Pass 5 Function of printing information of student Selection 2: None Display all information(ID, grades) student was entered. Accepted Pass 6 Function ofprinting student has highest grades Selection 3: None Display the student has highest grades(grades,ID) Accepted Pass 7 Function of printing student has lowest grades Selection 4: None Display the student has lowest grades(grades,ID) Accepted Pass
- Test case 1: *+A, b, c, , , A&..
- Test case 2: *+A, b, c , , &, … +1, 2 ,
+Duplicate:
- Test case 4: *+A, b, c, , &, … +1, 2, 3
- Test case 5: None
- Test case 6: None
- Test case 7: None IV. Evaluation of code After testing and checking my application error, I found that my application:
▪ Advantages:
- The menu interface is completed neatly and can be easily managed by the user.
- The program can store student’ mark and ID and display them on screen and find maximum or minimum grades.
- The program can check the ID is duplicated or not and if the grade input is valid or not.
▪ Disadvantages:
- When you enter the wrong data type, the application will error, as you can see when I entered ID student with type characters.
