Vb编写程序，随机生成 10 个[1，100]的整数，输出其平均值及大于平均值的数。
程序如下：
Private Sub Form_Activate()
Dim a(1 To 10) As Integer '定义存放10个小于等于100的整数数组
Dim sum, i, max, min As Integer '定义sum存放10个数的和，min放10个数中最小值，max放最大值，i循环控制变量
Dim aver As Single '定义aver放平均值
sum = 0
max = 0
min = 100
Randomize
For i = 1 To 10 '生成随机数存入数组，并求出和、最大值、最小值
a(i) = Int(Rnd * 100 + 1)
sum = sum + a(i)
Print a(i)
If a(i) > max Then max = a(i)
If a(i) < min Then min = a(i)
Next i
aver = sum / 10
Print "平均数是" & aver
For i = 1 To 10 '逐渐改变最大值、最小值与平均值最接近的
If (a(i) aver) Then max = a(i)
If (a(i) >= min) And (a(i) < aver) Then min = a(i)
Next i
If (max - aver) > (aver - min) Then '找到最接近的值
Print "最接近平均值得数是" & min
Else
If (max - aver) < (aver - min) Then
Print "最接近平均值得数是" & max
Else
Print "最接近平均值得数是" & min & vbTab & max
End If
End If
End Sub
运行结果如下：
Option Base 1
Private Sub Command1_Click()
Randomize
Dim i As Integer, a(10) As Integer, s As Integer, valAverage As Single
For i = 1 To 10
a(i) = Int(Rnd(i) * 90 + 10)
Print a(i);
s = s + a(i)
Next i
Print
valAverage = s / 10
Print "平均值为：" + CStr(Format(s / 10, "##.000"))
For i = 1 To 10
If a(i) > valAverage Then
Print a(i);
End If
Next
Print
Print
End Sub
Private Sub Command1_Click() '生成10-100间10个数字求平均值及大于平均值的数字

Dim a() As Integer, i As Integer, he As Integer
Dim pj As Single

For i = 0 To 9
Print a(i);
he = he + a(i)
Next i
pj = he / 10

Print Format(pj, "0.00"): Print "大于平均值的数字为" & Space(2);
For i = 0 To 9
If a(i) > pj Then
Print a(i);
End If
Next i
End Sub
Private Function ProduceShu(ByVal m As Integer, ByVal n As Integer, _
ByVal num As Integer, a() As Integer) As Integer '生成10个数字
Dim i As Integer
ReDim a(num)
For i = 0 To num - 1
Randomize
a(i) = Int((n - m + 1) * Rnd + m)
Next i
End Function
