我正在制作一个计算成绩的程序。我的参与分数是基于你缺课的天数。

这是我想要编程的。

根据用户输入，我将错过的日子保存为 AB1。

那么 AB2 应该是我的参与分数

参与分数是基于 100 分 如果你错过了 2 节课，那么你有 100 分。然后，在 2 之后的每一天，您错过了 20 分。你也不能负分。所以这就是我想说的。

如果您错过 2 天或更短的时间。您的参与分数是 100。如果您错过 3 到 6 天，您的分数是 80,60,40,20 如果您错过 7 天或更多，您的分数是 0。

 Sub Main()
    Dim TG1 As Integer = -1
    While TG1 < 0 Or TG1 > 200
        Console.WriteLine("Please enter your grade for project #1 <0-200>: ")
        TG1 = Console.ReadLine()
    End While

    Dim TG2 As Integer = -1
    While TG2 < 0 Or TG2 > 200
        Console.WriteLine("Please enter your grade for project #2 <0-200>: ")
        TG2 = Console.ReadLine()
    End While

    Dim TG3 As Integer = -1
    While TG3 < 0 Or TG3 > 200
        Console.WriteLine("Please enter your grade for project #3 <0-200>: ")
        TG3 = Console.ReadLine()
    End While

    Dim MT1 As Integer = -1
    While MT1 < 0 Or MT1 > 150
        Console.WriteLine("Please enter your grade on the midterm <0-150>: ")
        MT1 = Console.ReadLine()
    End While

    Dim AB1 As Integer = -1
    While AB1 < 0 Or AB1 > 30
        Console.WriteLine("Please enter how much you were absent   <0-30>: ")
        AB1 = Console.ReadLine()
    End While

    Dim AB2 As Integer
    If AB1 <= 2 Then AB2 = 100
    If 2 < AB1 < 8 Then AB2 = 100 - ((AB1 - 2) * 20)
    If AB1 > 7 Then AB2 = 0

    Dim GSF As Integer
    GSF = TG1 + TG2 + TG3 + MT1 + AB2

    Dim PNA As Integer
    PNA = 900 - GSF

    Dim PeNA As Integer
    PeNA = PNA / 150



    Console.WriteLine("------------------------------------------------")
    Console.WriteLine("--GRADE SUMMARY--")
    Console.WriteLine("Project #1    : {0}", TG1)
    Console.WriteLine("Project #2    : {0}", TG2)
    Console.WriteLine("Project #3    : {0}", TG3)
    Console.WriteLine("Midterm Exam  : {0}", MT1)
    Console.WriteLine("Participation : {0}", AB2)
    Console.WriteLine("-------------------------------------------------")
    Console.WriteLine("Total grade so far: {0}", GSF)
    Console.WriteLine("")
    Console.WriteLine("{0} {1} {2}", "Desired grade".PadRight(20), "Points needed".PadRight(20), "Percentage needed on final")
    Console.WriteLine("{0} {1} {2}", "A".PadRight(20), PNA.ToString.PadRight(20), PeNA.ToString.PadRight(20))


    'A - 900-1000
    'B - 800-899
    'C - 700-799
    'D - 600-699

If 2 < AB1 < 8 Then

可能不会像你想的那样做。它可能应该是

 IF 2 < AB1 ANDALSO AB1 < 8 THEN...
