Question $2$

Suppose you are working on a program that manages student records. Each student record contains the following information:

Student ID $($an integer$)$

Student Name $($a string$)$

Scores in three subjects $($each score is a float$)$

You are required to write a program that performs the following tasks:

Define a structure named "Student" that contains the above information.

Define an array of "Student" structures to hold the records of $20$ students.

Write a function named "readStudents" that reads the student records from a file named "students.txt$"($you are required to create the file first$)$ and stores them in the array of "Student" structures.

Write a function named "printStudents" that prints the student records in the following format:

$\backslash$table$[[$ID$,$Name,Subject $1,$Subject $2,$Subject $3,$Average Score$],[1,$John Doe,$75\mathrm{.}50,80\mathrm{.}00,85\mathrm{.}50,80\mathrm{.}00],[2,$Jane Smith,$80\mathrm{.}00,85\mathrm{.}50,90\mathrm{.}00,85\mathrm{.}50]]$

Write a function named "writeStudents" that writes the student records from the array of "Student" structures to a file named "report.txt$"$ in the same format as above.

Calculate and print the average score of each subject.

Your program should have a main function that calls the above functions in the following order:

$$ readStudents

$$ printStudents

$$ writeStudents

The program should display the average scores for all students to the output console.
