CBCP2101 Computer Programming I: Developing a Student Grading System

This assignment solution details the development of a student grading application. It begins with an analysis of the problem, identifying the need for variables to store the number of students and courses. The application then takes student IDs and marks for each course as input. It calculates grades based on predefined mark ranges (A to F) and computes the average mark. Finally, it determines whether the student can proceed to the next semester based on whether the average mark is greater than or equal to 40. The solution includes a pseudo code algorithm, a flowchart, and a tracing table to illustrate the application's logic and functionality.

Analysis of the problem and identification of required items
For the student grading application, at first it is important to get the total number of student for whom
the grading process will continue. Therefore, at first there should be a integer variable that will store the total
number of students for whom the application will calculate the grades. More over the application will also
contain an integer that will contain the number of courses that for every student.
In the next stage, the application will ask for the student ID and marks in the different courses to
calculate the average marks for every student. Now for marks in each course the program will check
conditions to determine and show grade for each of them. At the end if the stored average value become greater
or equal to 40 then the program will print “Proceed to next Semester”. Otherwise the program will display
“Fail”.
Algorithm in a pseudo code
Following is the pseudocode for the grading application,
Step1: Start
Step2: Read total number of students
Step3: Read the number of courses for the semester.
Step4: Read the student ID.
Step5: Read the marks for the different courses for the student.
Step6: show grades for the courses.
If (marks 80 ≤ marks ≤ 100) show Grade A.
Else If (marks 70 ≤ marks ≤ 79) show Grade B.

Else If (marks 60 ≤ marks ≤ 69) show Grade C.
Else If (marks 50 ≤ marks ≤ 59) show Grade D.
Else If (marks 40 ≤ marks ≤ 49) show Grade E.
Else (show Grade F.)
Step 7: Show average marks for all the courses.
Step 8: IF average marks are less than 40 display “Failed”.
Else
Print “Proceed to next Semester”
Ask for Next student ID
Go to step 4;
If (reached maximum number of student)
Stop
