Part 1

Fulton College wants an application that will allow the lecturers to store information regarding the students and their marks.

Create a Windows application that uses variable arrays to store the student's name and their mid semester marks. (Your application should at least store records for 10 students.)
For example:

Dim strNames() As String = {"Hova", "Nemo", "Zoc", "Lucas", _
"Phuket", "Cindy", "Marlin", "Darla", "Nigel", "Cindrella"}
Dim dblMarks() As Double = {32.5, 88, 90.5, 67.5, 65, 77.5, 85, 78.5, 89.5, 90}

Have a command button that when clicked produces various statistics, such as:

- Average mark

- Highest mark scored and the student who scored it. (* There are no ties) ‘

- Lowest mark scored and the student who scored it (** There are no ties)

- The range (i.e. Highest score - lowest score)

Use functions

Convert the solution to use functions. That is create and use functions for:

- Average mark
This function should accept the dblMarks array as input and return the average as result.

- Highest mark scored
This function should accept the dblMarks array as input and return the highest score.

- Lowest mark scored
This function should accept the dblMarks array as input and return the lowest score.

- The range
This function should accept the highest and lowest score as input and return the range.

Part II: A Program to Analyze Exam Results (using structure arrays)

Modify Part I so that the data on student names and marks are stored in a structure array of type Student.

Declare the following structure at module level:

Structure Student
Public strName As String
Public dblMark as String
End Structure
And then in the click event handler of command button that calculates the statistics; declare a array and populate it with the same data. e.g.
Now in your code for the calculations, every where you used dlbMark, replace that line with
StudentMarks(index).dblMark, where index is the loop control variable

Part III: A Program to Analyze Exam Results (using files and arrays)
Create a file called marks.tx that will store the data on student's name and their mid-term mark Example: Given below are the contents of the file marks.txt.

Create a "File" Menu and then an "Open File" menu item under it. Program the following requirements under the click event-handler of the "Open File" menu item.

- Use a FileOpenDialog dialog box to locate and get the file path for marks.txt (you can download this file and save it in your USB or to any other appropriate directory)

- Once file is selected, open it and using a loop read the entire contents of the file line by line, extracting name and mark and storing them in the names and midterm marks array.

You program will still require the following array (declared at module level), however without the initialization.
