I. SOLVE PROBLEM AND RESULT
- Problem: A math teacher wants to manage grades of a class. He asks you to help him to write a small application to do that. He needs to enter student IDs, studentās grades and store these information into 2 separate arrays (integer array for IDs and float array for grades). Then he needs to print all student IDs together with their grades. Finally, he needs to know which student has highest grade and lowest grade. Your program should be menu based with the options above. When an option is done, the program should go back to the main menu so he can choose another option. There should be an option to quit program.
- Solvable problem: I write a program is used to manage student information. The main functions of program is:
- Input student information (Student ID, Student Grades)
- Display student information (Print to the screen)
- Find the student has highest grades
- Find the student has lowest grades
- Exit
- Explanation code : a. Global variables:
- In this program, I use 3 libraries which are stdio.h, stdlib.h and string.h
- Students for total students, ID[30] for ID, grade [10] for grade Figures:1 Global variables of program. b. Function input information of studentās:
- This code help you check if you have entered the recently entered ID, use the for loop to check in the array id.
Figures:4 Find the highest grades of student. d. Function find the lowest grades of student:
- Help you find the student has lowest grades and print to the screen.
- Print the result on the screen Figures:5 Find lowest grades of student. e. Menu Options:
- Helps to display more options in the menu.
- Example: input student ID & grades, view student, find the highest or lowest grades of student, exit program.
This menu have 5 option for choose, if you choose <1 or >5. Input will invalid and choose again. Figures:6 Menu options of program. II. RESULT
- Result for the case data 1: We will input the proper information in this situation. To begin, the system will display a menu with five alternatives. We must choose one of them (from option 1 to
- and add it to the menu. For example, pressing number 1 will produce a list including all of the studentsā IDs and grades. After that, we must input the number of students in the class, their IDs, and their grades. Figures:7 Enter option 1
Press number 3 to display all of students have highest grade and IDs student in class. Otherwise, press 4 to look for all of student and IDs student have lowest grade. Figures:11 Find the highest grade and IDs Figures:12 Find the lowest grade and IDs Finally, press number 5 to exit program Figures:13 End the program
- Result for the case data 2: In case 2, Iāll go through some of the most typical errors that people make. To begin, Iāll choose wrong selection. For example, if the user donāt select choice 1- choice 5, system will prompt the user to input again.
Figures:14 Choosing an invalid option When you input duplicated IDs, the user need input again. Figures:15 Entering duplicated IDs When you type negative number in grade, user need to tap right number. Figures:16 Entering negative grade III.

TC4 - Input choice 4
Submit Find studentsā who has lowest grades Passed TC5 - Input choice 6
Submit Failed Try other number (1-5) TC6 - Input choice 1
Submit Enter number of student: 31 and - 4 Failed Try number in range (1-30) TC7 - Input choice 1
Submit Enter number of student: 1 Enter Studentsā ID: GCD Enter studentās grade: 6
|ID:
GCD201871|
|Grade: 6| Failed Donāt type the works TC8 - Input choice any words
Submit Failed Donāt type the words TC9 - Input choice 5 Tap any key to exit Passed
- Conclusion Examine the results of the tests in order to plan for future maintenance: During the design and testing process, we discovered a few weaknesses that will need to be fixed in the future. First, if a user enters an ID that contains a character, the system would
exit rather than prompting the user to submit a valid ID and the system will run that prompt continuously and you can't enter anything.
- Evaluation of program: a. Advantage:
- Can store studentsā mark and ID, display them on screen and find maximum or minimum grade.
- Can find the highest or lowest grade clearly and fast and print all studentās IDs.
- Can check if the ID is duplicated or not and if the grade input is valid or not b. Disadvantages:
- Application will error when entering the wrongs data types, you can see when I entered ID student with types characters, application will error.
- Menu interface is not completed beautifully.
- Infinity loop when enter ID with word. Although there are many errors that have not been resolved, but basically my application has met the basic need of a student management software, the rest I will fixed in the future.
