The task involves modifying a conversion program to enhance its functionality for handling multiple grades and calculating overall averages. Specifically, the program should be adapted to allow users to input up to ten grades in categories such as Assignments, Discussions, Attendance, and two separate grades for Tests. Once the data entry is complete, the program must compute the average grade for each of these groups. Finally, it should determine the total course grade, expressed both as a numerical value and as a letter grade, based on specified weightings: Assignments (30%), Discussions (30%), Attendance (10%), and Tests (30%).

In the context of the programming language C, this involves creating arrays to store grades, implementing loops to handle user input, and computing averages by summing array elements and dividing by the number of entries. For the calculation of the overall grade, each category's average must be multiplied by its weight, and the sum of these weighted scores provides the total grade. The letter grade is then assigned based on conventional grade thresholds (e.g., A, B, C, D, F).

This approach enables a more flexible and comprehensive grading tool that can better reflect student performance across multiple assessments. Such modifications also reinforce fundamental programming concepts such as array handling, control structures, input/output operations, and conditional logic. The program's structure should be modular, with functions dedicated to input collection, average calculations, and final grade determination, promoting clarity and maintainability.

Implementing these features in C requires careful attention to detail, including input validation to prevent errors, proper formatting of output for clarity, and handling edge cases such as all zero grades or incomplete data. Overall, the project provides practical experience in applying programming skills to real-world grading scenarios, enhancing both functionality and user experience.
