我正在Visual Studio Express 2012中完成一项任务,挑战要求我创建一个应用程序,允许用户输入三个跑步者的名字和完成时间。我正在为第一,第二和第三名获胜者制作If ... Then ... Else部分的流程图。任何人都可以帮助我或引导我在正确的方向上创建条件语句部分吗?

这就是我所拥有的:

If intRunner1 < intRunner2 And intRunner1 < intRunner3 Then
    lblDisplay.Text = "First Place"
End If
If intRunner2 < intRunner1 And intRunner2 < intRunner3 Then
    lblDisplay.Text = "First Place"
End If
If intRunner3 < intRunner1 And intRunner3 < intRunner2 Then
   lblDisplay.Text = "First Place"

我也有:

If intFinish1 < intFinish2 Then
    If intFinish1 < intFinish3 Then
        lblFirstPlace.Text = "Runner 1 finished in first place."
    Else
        lblSecondPlace.Text = "Runner 1 finished in second place."
Else
    If intFinish1 < intFinish3 Then
        lblFirstPlace.Text = "Runner 1 finished in second place."
    Else
        lblThirdPlace.Text = "Runner 1 finished in thirdplace"
    End If
End If 

1 个答案:

答案 0 :(得分:0)

  1. 如果同时输入所有数据:
  2. 你应该制作大小等于跑步者数量的2d数组。在第一维中插入跑步者的名字,在第二维中插入跑步者的时间。然后在第二维上对此数组进行排序以获得获胜者。由于范围非常小并且仅用于演示,您可以使用if then else条件来检查排序。

    1. 如果您一次输入一个跑步者
    2. 只需按正确的顺序在2d数组中插入跑步者,然后在插入所有数据后输出数组以获得获胜者名单。

      例如第二种方法的伪代码:

      create 2d array A
      repeat for each runner
        input runner name
        input runner time
           if A has runners
            check runner against each runner in A
                  insert runner at the correct position
           else
             insert runner in A
      end repeat
      
      1. 如果你只使用变量而不是数组:让我们假设你有跑步者A B&amp; C 这些是可能的情况:ABC,ACB,BAC,BCA,CAB,CBA 你必须检查每一个。
      2.     Take A
               if A beats B (then he is definately second or first)
                 if A beats C (then he is definately first)
                   A is first
                   if B beats C
                      B is second, C is third
                   else 
                      C is second, B is third
                 else
                   A is second
                   if B beats C
                      B is first, C is third
                   else 
                      C is first, B is third
               else ... if A beat C.... and so on
        

        预测此项以检查每种可能的情况。
