Help on writing C program for this problem?

In this assignment, you are required to write a program that reads the content of a file (the name of the file is the first command line argument). The number of lines in the file is not known (it could be thousands of lines). But each line is of this format: name GPA Example (students.txt): Mary 4.0 Jack 2.45 John 3.9 Jane Mike 3.125 3.8 Your program should read all the lines and store each line as an element of an array: You should create a struct named Student which has a name and a GPA. Your program should then print a sorted list of students whose GPA is greater than 3.9. The list should be sorted by GPA in descending order
