Question

Im trying to write up a code where two txt files are being compared to each other. One text files has the answer like “TFTTFFT” and the other txt files has the result including id like “1234 TT-FFT” The crazy part is that for each correct answer, the student gets 4 points and for every incorrect answer, the student gets -1 and for every no answer, which in this case is represented by a dash(-), the student gets zero. How do i go about writing up a code for this? ANy help will be very much appreciated. I don’t necessarily need some one to code this for me as i have pretty much done the opening of files and storing them in appropriate variables. Just a feed back on how to go about doing this would be nice. Thank you in advance.

Update :
I have revised the whole code and will put it up for consideration. Thank you Josh and thank you all those who have contributed so far. Please do let me know further what you guys think of the revised coding.

Update : Program not working 🙁

Answer 1

    Dim answers As String = 'Text from the answor file
    Dim student As String = 'Text from the student file

    ' a will be used to hold the first char from the answers file
    ' s will be used to hold the first char from the student file
    Dim a As String
    Dim s As String

    ' veriable that holds the student grad
    Dim grade As Integer = 0

    ' loop while we still have an answer
    While answers.Length > 0

        ' get the first answer and student respond
        a = answers.First
        s = student.First

        ' compare the two and update the student grade accourdingly
        If a = "-" Then
            grade = grade - 1

        ElseIf a = s Then
            grade = grade + 4
        Else
            grade = grade - 1
        End If

        ' remove the first answer from the two strings
        answers = answers.Substring(1)
        student = student.Substring(1)
    End While


    return grade
