数学题1~33个数字，要每6个数字相加
下面是设计的程序。
核心是如何把33个数中取3个的所有组合都搞出来。
Private Sub Command5_Click()
Dim a(1 To 6) As Integer
k = 6: duoshao = 0
For i = 1 To 6: a(i) = i: Next
Do
he = 0
For i = 1 To 6: he = he + a(i): Next
If he = 100 Then
For i = 1 To 6: Text1。 Text = Text1。Text + Str(a(i)) + " ": Next
Text1。Text = Text1。Text + vbC...全部
