Explanation:
-
Input:
- The program prompts the user to enter the number of students in each section (A, B, and C).
- For each student in a section, the user provides marks for 5 subjects.
-
Total Calculation:
- For each section, the total score is calculated by summing up the marks of all students for all subjects.
-
Average Calculation:
- The program calculates the average score for each section by dividing the total marks by the number of students and subjects in that section.
-
Comparison:
- The averages of the sections (A, B, and C) are compared to determine the section with the highest average score.
-
Output:
- The average score for each section is printed, followed by a statement declaring the section with the highest average score.

What the Students Will Learn:
- Loops: The program demonstrates nested loops for input and processing of data.
- Arrays: Arrays are used to store total marks and averages for each section.
- Conditionals: The comparison logic helps students understand the use of
if-elsestatements. - Input/Output Handling: Students learn how to gather input from the user and output formatted results.
- Data Validation: Students can expand this project to handle data validation, such as ensuring marks are within a valid range (0 to 100).
This project not only reinforces basic programming concepts but also teaches students how to structure and process data logically. They can further extend the program by adding features like handling ties, or calculating performance across more subjects.
