What's Wrong With this Code? (#3)

Tuesday, August 15, 2006

Here is a Visual Basic program with bowling scores in a multi-dimensional array. Two players bowled three games each. The program tries to display the total score for each bowler, but has a small problem. Can you spot it?

Module Module1

  Sub Main()

    Dim allScores As Integer(,) = _
        {{101, 128, 143}, {123, 115, 116}}

    ' for each player
    For i As Integer = 0 To allScores.GetUpperBound(0)

      Dim score As Integer

      ' for each game
      For j As Integer = 0 To allScores.GetUpperBound(1)
        score = score + allScores(i, j)
      Next

      Console.WriteLine("Player {0} score: {1}", i + 1, score)

    Next

  End Sub

End Module
