use c# Write a program to perform student record manage for class IST$311.$ It contains two parts: student record class $($from A$2)$ and main program. It should get the student information from the user and set up student record class array with proper size. The program will perform sorting student record by last name then first name, compute final grade, search highest final grade student, and then display this student$$s information by use ToString$()$ method.

Part I: Student class from A$2$

Student class definitions:

It should contain first name, last name, $3$ exams grade, $5$ labs grade, final grade. Its member functions are default constructor, $2$ copy constructors, display student$$s information and override ToString$(),$ which only display class type, last name, first name, and final grade.

$($Note: $3$ exam grades and $5$ lab grades are stored in an array with $8$ elements, final grade should be read only attribute$)$

Student class implementation:

The student class attributes: It should have basic accessor methods $($get and set$).$

Default constructor: It sets student class variables to default value. String variables set to $$None$,$

double variable set to $0,$ and all elements in the array set to $0.$

$2$ Copy constructors: It sets student class variables for student$$s information by different number of passes in parameter list. Another one pass in class object for sets student$$s information.

ComputeGrade$()$ method: It base on the $\%$ of final grade to compute final grade as follows:

Lab$$s grade is $50\%$ of final grade.

Exam $1$ and exam $2$ are $15\%$ of final grade.

Exam $3$ is $20\%$ of final grade.

Note: final grade should display $2$ digits after decimal. It should be private access modifier and called by all constructors of Student class.

DisplayAllGrade$()$ method: It should return string as student$$s information in following sequence with

proper format: Last name, First name, Exam $1,$ Exam $2,$ Exam $3,$ Lab $1,$ Lab $2,$ Lab $3,$ Lab $4,$ Lab $5,$ Final Grade $($Note: it should not display title in the method$)$

override ToString$()$ method: It should use GetType$()$ to return string as student$$s information in

following sequence with proper format: GetType$(),$ Last Name, First Name, Final Grade

Part II: main program:

The main program begins with ask the user how many students record first, then enter each student$$s information to set up student record array. Compute all of student$$s final grade in the student record array. Then, call sort method to sort the student record array by last name then first name. Next, display all students list information use Student class DisplayAllGrade$()$ method. Final action search highest final grade student in the student record array and use Student class ToString$()$ method to display highest grade student$$s information.

Three methods:

$1.$ Write $$readdata$$ method implementation to read the data from the user and store into student record array.

$2.$ Write $$sorting$$ method implementation to sort the student record array by last name, then first name. $($You need to use Array.sort$()$ method, which Student class inherited IComparable library and provide override CompareTo$()$ method in IComparable library for Student class object.$)$

$3.$ Write $$searchHighestGrade$()$ method implementation to search and return the index of array that has highest final grade student.

Output Example:

LastName, FirstName exam$1$ exam$2$ exam$3$ lab$1$ lab$2$ lab$3$ lab$4$ lab$5$ final

Anderson, Baily $678975928378686777\mathrm{.}20$

Thomas, Daily $998877665544332265\mathrm{.}45$

Thomas, Eason $678779905675898878\mathrm{.}70$

Woo, Alice $887766554487968174\mathrm{.}25$

Highest grade in IST$311.$Students is Thomas, Eason$$s final grade $78\mathrm{.}7.$
