Read the data from the student.txt file and store it in a suitable data structure. The operations that should be allowed are

1. List the courses taken by a particular student
2. List the students enrolled for a particular year
3. List students enrolled for a particular course Take input from the user to perform the above operations.

Maintain different C files for different tasks such as

• file operations in a separate file
• data structure operations in a separate file Divide operations suitably in different files.

Use "Makefile" to compile different files and execute the program.
