Sure! Here's a simple case study idea that involves formula and calculations in C:
Case Study: Grade Calculator
Description:
Create a program that calculates the average grade of a student based on their scores in different subjects and displays the corresponding letter grade.
Requirements:
1. The program should prompt the user to enter the number of subjects.
2. For each subject, the program should ask the user to enter the score.
3. Calculate the average grade by taking the sum of all the scores and dividing it by the number of subjects.
4. Display the average grade along with the corresponding letter grade using the following scale:
- 90 and above: A
- 80-89: B
- 70-79: C
- 60-69: D
- Below 60: F
Example Output:
Enter the number of subjects: 5
Enter score for subject 1: 80
Enter score for subject 2: 90
Enter score for subject 3: 70
Enter score for subject 4: 85
Enter score for subject 5: 95
Average Grade: 84
Letter Grade: B
This case study will allow you to practice taking input from the user, performing calculations, and displaying the results. Additionally, you can enhance the program by adding error handling for invalid inputs and expanding it to include more grading criteria.
