Introduction:
Write a C# program which allows the user to enter student information and outputs the appropriate grade for the student. This assignment involves the use of classes, arrays or collections, loops and methods.
Result Class:
Create a class called Result.cs which serves as the main class. This class will first prompt the user for number of student records. You will create an array based on this information. The program reads a list of student names, marks and grades into an array. This is done using a loop and prompting the user to enter the names and marks, one by one. (The student name should not be duplicate).The grade is automatically computed based on the mark provided. The Result class shall include the following options:
1. Display a Student Mark
2. Change Student Mark
3. Print out information for all students
4. Exit program
Student Class:
Create a class called Student.cs. This class contains the following:
a) class data fields name, mark and grade
b) public Student (string name, double mark, string grade)
// constructor
c) public string getName() / / to return name of student
d) public double getMark() // to return mark of student
e) public string getGrade() // to return student grade
f) public void setMark(double mark) // to set student mark
g) public string setGrade(double mark) // mark is first checked using a nested if-else and switch to determine grade.
The possible grades are:
0 <= mark < 50 -
50 <= mark < 60 -
60 <= mark < 70 -
70 <= mark < 80 -
80 <= mark < 100 -
