问题描述：
VB中在一段英文字母中 统计哪个字母出现的最多,次数是多少 有段代码求解释!
Dim k,c1,c2,c3,avg,num As Integer
avg = 0
num = 0
For k = 1 To 100
c1 = Int(a(k) / 100)
c2 = Int((a(k) - c1 * 100) / 10)
c3 = a(k) Mod 10
If a(k) = c1 ^ 3 + c2 ^ 3 + c3 ^ 3 Then
avg = avg + a(k)
num = num + 1
End If
Next k
Dim k,c1,c2,c3,avg,num As Integer
avg = 0
num = 0
For k = 1 To 100
c1 = Int(a(k) / 100)
c2 = Int((a(k) - c1 * 100) / 10)
c3 = a(k) Mod 10
If a(k) = c1 ^ 3 + c2 ^ 3 + c3 ^ 3 Then
avg = avg + a(k)
num = num + 1
End If
Next k
