题目

VB编程数据文件里的前10000个数从小到大排列,前5000个数中能被3整除的数的个数

答案

假定10000个数在全局变量的数组a里,
Sub sort()
For i = 1 To 9999
k = i
For j = i + 1 To 10000
If a(j) < a(k) Then k = j
Next j
t = a(i): a(i) = a(k): a(k) = t
Next i
调用sort过程就能对10000个数排序.
调用Mycount函数就能统计前5000个数中能被3整除的数的个数
Function mycount() As Integer
Dim x As Integer
x = 0
For i = 1 To 5000
If a(i) Mod 3 = 0 Then x = x + 1
Next
mycount = x
End Function
