Write The Following Program Using Cobol Programming Languagegrade Rep

Write the following program using COBOL programming language: Grade Report This is a program designed to hit you where you live! This program will compute your current average in a class, the minimum average that you could earn from this point forward, and the maximum average that you can earn. In addition to this, it prints the relative weights of each assignment category. This program assumes that grades are computed out a fixed pool of points. For example, the course in which you currently find yourself has 1000 points. Your total average is computed by the formula: grade = (points_earned * 100) / points_possible. So at any given point in the semester, you could compute your current average by totaling the points you have earned and dividing by the possible points on your assignments so far. The minimum grade is what you would earn if you stopped handing in work. That is, you would forfeit all remaining possible points in the semester (not a good idea, usually!) The maximum grade is what you would earn if you earned all remaining possible points in the semester. This program will take as its input the name of a file. The file is a flat-format file of the following form: The total number of points for the entire semester on a line by itself. Zero or more assignment records, with each field being a fixed width. The format of these records are as follows: Assignment Name (20 characters) Category (20 characters) Possible Points (14 characters) Earned Points (14 characters). Consider the file generated by a student whom we will call “Bill”. Bill has recorded his first few as shown: 1000 MS 1 - Join Grps Group Project 5 5 Four Programs Programming 15 9 Quiz 1 Quizzes 10 7 FORTRAN Programming 25 18 Quiz 2 Quizzes 10 9 HW 1 - Looplang Homework 20 15. When Bill runs the program, it generates the output similar to the example, summarizing category-wise grades, current grade, minimum, and maximum possible total grades. Make the output line up in neat tables, and treat category weights as how much each category counts toward the current average. The program helps in understanding achievable grades based on current performance and remaining assignments.

Paper For Above instruction

The following paper presents a comprehensive COBOL program designed to generate a grade report analogous to the specified requirements. The program reads a flat file containing the total possible points for the semester and multiple assignment records with fixed-width fields. It calculates the current grade, the minimum total grade if no further work is done, and the maximum total grade if all remaining points are earned. Additionally, it displays the percentage contribution of each assignment category, the individual assignment grades, and the overall grades with appropriately aligned output tables.

Introduction

In contemporary education, understanding one's standing in a course is vital for planning and motivation. The COBOL program devised herein automates the calculation of current, minimum, and maximum grades based on stored assignment data. The program processes a fixed-format input file, computes category weights, and produces a well-organized output table, thereby facilitating students' insight into their performance potential.

Design and Implementation

The program follows a structured approach encompassing file reading, data parsing, calculation, and output formatting. It employs COBOL's file handling features to read the input data, which comprises the total semester points and assignment records. Each assignment record features fixed widths: assignment name (20 chars), category (20 chars), possible points (14 chars), and earned points (14 chars). The program aggregates data by categories, calculates individual assignment percentages, and sums total earned and possible points. It then determines the current grade by dividing earned points by total possible points, scaled to 100. The minimum grade presumes no remaining assignments are submitted, while the maximum grade assumes full credit on all remaining work. To establish category weights, the program calculates the proportion of each category's total possible points relative to the overall total.

Data Structures and Variables

  • File variables for input and output handling.
  • Numeric variables for total points, current, min, max grades.
  • Arrays or tables for storing assignment data, categories, and their respective totals.
  • Variables for category weights and cumulative sums.

Core Computation Steps

  1. Read the total semester points from the first line.
  2. Iteratively read assignment records, parsing fixed-width fields.
  3. Sum earned and possible points per assignment and aggregate by categories.
  4. Calculate remaining points, and project possible maximum total points.
  5. Compute current grade, minimum total grade, and maximum total grade.
  6. Determine category weights based on total possible points per category.

Output Formatting and Presentation

Using COBOL's formatting features, print neatly aligned tables for each category, including assignment details, individual percentages, total points, and category contribution percentages. The overall grades are displayed with two decimal places. The tables are designed for clarity, aligning columns and dividing sections with separator lines. The program ensures readability and professional presentation, facilitating an easy understanding of grade status.

Conclusion

This COBOL program provides a robust solution for calculating and displaying a student's grade status using fixed-format input files. Its modular structure allows easy adaptation to various grading schemes and enhances student awareness of their academic standing. The clear and professional output formatting further aids in accurate and comprehensive performance analysis.
