Write a program that uses a structure to store the following data:

Member Name Description

Name Student Name (string)

IdNum Student ID Number (int)

Tests Pointer to an array of test scores (double*)

Average Average test score (double)

Grade Course grade (char)

Two example text files called student1.txt and student2.txt (attached with this document on black board) that contain information of several students are given to you. The first column is the name of the student (assume only one word), the second column is the student ID number; the remaining columns indicate the scores in different tests made by the student. In student1.txt, each student has 6 test scores, while in student2.txt each student has 5 test scores. The program should first ask the user the name of the file, how many test scores each student takes and how many students are there in the file. Depending on the number of students it should dynamically allocate an array of student structures. The program should read the file and fill up the three members (Name, IdNum, and Tests) of the each student structure. Each structures Tests member should point to a dynamically allocated array that holds the test scores. After each student structure has been filled up, the program should calculate the average score of each student and store it in average member of each structure. The course grade should be computed based on the following basis:

Average Test Grade Grade

90-100 A

80-89 B

70-79 C

60-69 D

59 or below F

The course grade should be stored in the Grade member of each structure. Once this data is calculated, a table should be displayed on the screen listing each student (name, ID number, average test score, and course grade) in descending order of their average test score.
