C# - C Sharp: Practical 7: Marks Management System

MARKS MANAGEMENT SYSTEM

1. Create an interface name IStudentMark contains these properties and methods:

a. Properties:

- FullName (string)

- ID (int)

- Class (string)

- Semester (int)

- AverageMark (float) – Read only property

b. Methods:

void Display()

2. Create a class name StudentMark:

a. Implements the IStudentMark interface in step 1.

b. The method Display() will print all FullName, ID, Class, Semester, AverageMark.

c. Declare an array name SubjectMarkList type int has size of 5 elements.

d. Create an indexer uses the array SubjectMarkList in step 2c.

e. Create a method named AveCal to set AverageMark = average of 5 int elements in SubjectMarkList array.

3. Display a tasks menu to choose:

4. If user type 1 from the keyboard then:

a. Create a new StudentMark  instance and input FullName, Class, Semester and then ask users to enter 5 subjectmarks and set to the instance indexer. The ID is auto increament (++ID ).

b. Create a Hastable (create only one Hastable only) to keep the StudentMark instance in step 4a with key = ID and value = the student instance.

5. If user type 2 from the keyboard then:

Loop from all studentmark instances in the Hastable then executes the Display() method from IStudentMark interface.

6. If user type 3 from the keyboard then:

Loop from all studentmark instances in the Hastable then executes the AveCal() method and then executes the Display() method.

7. While user not chooses Exit (type 4 from the keyboard) then go back to the menu step 3 to ask user chooses an option.
