谁帮我解释一下这些代码是什么意思,
Function isprime(t_i As Integer) As Boolean
Dim j As Integer
isprime = False
For j = 2 To t_i / 2
If t_i Mod j = 0 Then
Exit For
End If
Next j
If j > t_i / 2 Then isprime = True
End Function
參考答案:Function isprime(t_i As Integer) As Boolean '定义isprime为布耳变量,t_i为整型参数
Dim j As Integer '定义J 为整型变量
isprime = False'初始化isprime为假
For j = 2 To t_i / 2'开始循环,J从2到t_i 除以 2
If t_i Mod j = 0 Then'如果j能被t_i整除
Exit For'则退出循环
End If'结束IF语句
Next j'否则继续循环
If j > t_i / 2 Then isprime = True '如果t_i除以2小于J则isprime为真
