Creating a Flowchart for Entering Marks and Displaying Grades of 40 Students
Efficiently managing student grades is a common task for educators. A well-structured flowchart can help streamline this process. This article covers how to design a flowchart for entering marks of 40 students and displaying their grades, along with relevant pseudocode. We will explore the steps involved and discuss how to represent them visually and logically.
Introduction
Managing the marks of 40 students involves multiple steps: entering individual marks, calculating the average, assigning grades based on predefined criteria, displaying the grades, and finally printing them. By breaking down these steps into a clear flowchart and pseudocode, the process becomes more organized and manageable.
Flowchart Structure
The flowchart for this task might look something like this:
Start: Initiate the process. Collect Marks: Input the marks of all 40 students. Store each mark in a list. Calculate Average: Compute the average of all the marks. Determine Grades: Use conditional statements to assign grades based on pre-defined criteria. Display Grades: Display the grades to the user. Print Grades: Print a list of all grades. End: Conclude the process.Pseudocode for the Flowchart
The following pseudocode represents the steps in detail:
procedure collect_marks for i 1 to 40 do input marks[i] end for end procedure procedure calculate_average(marks) sum 0 for i 1 to 40 do sum sum marks[i] end for average sum / 40 return average end procedure procedure determine_grades(average, marks) for i 1 to 40 do if marks[i] > 90 then grade 'A' elsif marks[i] > 80 then grade 'B' elsif marks[i] > 70 then grade 'C' elsif marks[i] > 60 then grade 'D' else grade 'F' end if records[i] marks[i] grade # storing grades and marks together for display end for end procedure procedure display_grades(grades) for i 1 to 40 do print grades[i] # output the formatted string containing mark and grade end for end procedure procedure print_grades(grades) open output_file for i 1 to 40 do write output_file, grades[i] # write each line to the output file end for close output_file end procedure
Explaining the Pseudocode
Collect Marks
procedure collect_marks for i 1 to 40 do input marks[i] end for end procedure
This procedure takes input for the marks of all 40 students and stores them in an array `marks[]`.
Calculate Average
procedure calculate_average(marks) sum 0 for i 1 to 40 do sum sum marks[i] end for average sum / 40 return average end procedure
This function calculates the average of all the marks entered by the user and returns it. It uses a simple summation method followed by division to compute the average.
Determine Grades
procedure determine_grades(average, marks) for i 1 to 40 do if marks[i] > 90 then grade 'A' elsif marks[i] > 80 then grade 'B' elsif marks[i] > 70 then grade 'C' elsif marks[i] > 60 then grade 'D' else grade 'F' end if records[i] marks[i] grade # storing grades and marks together for display end for end procedure
This function determines the grade for each student based on a set of predefined boundaries and stores the grades along with the corresponding marks in an array `records`.
Display Grades
procedure display_ for i 1 to 40 do print records[i] end for end procedure
This procedure prints the grades corresponding to each student. Each grade is displayed in the format 'Mark:Grade'.
Print Grades
procedure print_grades(records) open output_file for i 1 to 40 do write output_file, records[i] end for close output_file end procedure
This function writes the grades to an output file for archival or record-keeping purposes. The grades and marks are written in a line-separated format for easy readability.
Conclusion
By following the flowchart and using the pseudocode provided, one can efficiently enter marks, calculate grades, and generate prints for a group of 40 students. This method ensures accuracy and consistency in the grading process, which is crucial for any educational institution.
