3:

Private Sub C1_Click()

Dim x As Integer

x = 18000

Do While x > 18001

If isprime(x) Then Exit Do

x = x +1

Loop

Text1.Text = Str(x)

End Sub

Close 1

End Sub

二：

2(1)： check1.value “” “#” text2.text

2(2)： 5 x str(x) >

3：

Dim i As Integer, j As Integer, n As Integer

For i = 1 To 7

For j = 1 To 7

If i = 1 Or i = 7 Or j = 1 Or j = 7 Then

Sum = Sum + a(i, j)

If a(i, j) Mod 7 = 0 Then n = n + 1

End If

Next j

Next i

lblFirst.Caption = Str(n)

lblSecond.Caption = Str(Sum)

三：

2(1)：<> or num >

2(2)：Avg is>=85 is>=60 end select n-1

3：

Dim b(20) As Single, i As Integer, j As Integer

Dim max As Integer

For i = 1 To 20

For j = 1 To 5

b(i) = b(i) + a(i, j)

Next j

b(i) = b(i) / 5

Next i

max = b(1)

For i = 2 To 20

If max < b(i) Then max = b(i)

Next i

Text2.Text = Str(max)

四：

2(1)：true abc n form1 form2

2(2)：0 sellength t text2.text

3：

If a(k) Mod 3 = 0 Then

num = num + 1

b(num) = a(k)

End If

Next k

For i = 1 To num - 1

For j = i + 1 To num

If b(i) > b(j) Then

t = b(i)

b(i) = b(j)

b(j) = t

End If

Next j

Next i

2(1)：> x < y

2(2)：list1,list2 l1.text l1.listindex list1.listcount-1

3：

For i = 1 To n

For j = 1 To n

If i = j Or i + j = 8 Then

If a(i, j) Mod 3 = 0 Then Counter = Counter + 1

End If

If i = j Then Sum = Sum + a(i, j)

Next j

Next i

lblFirst

總結(jié)
