Looking for keen CMD App Tutor

[Willis1]

I have a project due in within the next couple of days - its a mathematical project where a menu driven command line app has to be created. There are several requirements for the app - including quadratic equations solver, monte-carlo inegration and prime numbers.

I have the full project requirements and criteria - anyone who's free to help etc. feel free to contact.

I would appreciate any sort of help

Thanks

There's lots of people that will help. What are you having a problem with. What have you tried? Are you getting errors? You should also post your current code that your having problems with.

[Willis1]

I have only started.

Module Module1
    'Application Title Screen
    Sub Main()

        Console.Title = ("Coursework Project - ")
        Console.SetCursorPosition(20, 10) 'This command centres the text on the screen
        Console.WriteLine("***COURSEWORK PROJECT - ***")
        Console.ReadLine()
        Console.Clear()

        Console.WriteLine("Coursework Project - ")
        Console.WriteLine("---------------------------------")
        Console.WriteLine()

        Console.WriteLine("Please choose from options 1-5")
        Console.WriteLine()
        Console.WriteLine("1. Accuracy Option")
        Console.WriteLine("2. Quadratic Equation")
        Console.WriteLine("3. Monte-Carlo Integration")
        Console.WriteLine("4. Prime Decision")
        Console.WriteLine()
        Console.WriteLine("5. Exit ")


        Console.ReadLine()

    End Sub


End Module

here's the outline of the project : https://drive.google.com/open?id=0B3...HRZMmJqUHEtWFE

My vb knowledge is very limited so I'm not even sure where to start :/

We can't do your homework for you, we can only give you examples and code snippets. Also I can't access your google drive because i don't have access i requested access, but until then i don't know the details, try screenshotting and uploading it to a post.

Check here: http://numerics.mathdotnet.com/ about half way down you will find the vb.net code.



I will be working to find more info for you

For Quadratic Equations:

Module Module1

    Sub Main()

        Dim a, b, c As Single
        Console.WriteLine("Write coefficient 'a'")
        a = Console.ReadLine
        Console.WriteLine("Write coefficient 'b'")
        b = Console.ReadLine
        Console.WriteLine("Write coefficient 'c'")
        c = Console.ReadLine
        
        Dim d As Integer = b ^ 2 - 4 * a * c
        If d >= 0 Then
            If d = 0 Then
                Console.WriteLine("Roots are real and equal")
            Else
                Console.WriteLine("Roots are real and different")
            End If

            Console.Write("Roots are: ")
            Console.Write((-b + d ^ 0.5) / (2 * a) & " , ")
            Console.WriteLine((-b - d ^ 0.5) / (2 * a))

        Else
            Console.WriteLine("Roots are complex")
            Console.Write("Roots are: ")
            Console.Write(-b / (2 * a) & "+" & (d * -1) ^ 0.5 / (2 * a) & "i")
            Console.Write(" , ")
            Console.WriteLine(-b / (2 * a) & "-" & (d * -1) ^ 0.5 / (2 * a) & "i")

        End If
        Console.ReadLine()

    End Sub

End Module

Looks like that code doesn't really work :/

But it gives you a idea.

Good working examples:

Do you understand the basics?

To give feedback you use the readline, then writeline to generate the response:

Module Module1
    Sub Main()
	While True

	    ' Read value.
	    Dim s As String = Console.ReadLine()

	    ' Test the value.
	    If s = "1" Then
		Console.WriteLine("One")
	    ElseIf s = "2" Then
		Console.WriteLine("Two")
	    End If

	    ' Write the value.
	    Console.WriteLine("You typed " + s)

	End While
    End Sub
End Module
