for i = 1 to 3
i=i+i
next
Msgbox i

一共循环3次,第一次 i=1 , i = 2, i= 3 ; 最后 i=i+i 就是 6 = 3+3 ,由于next 后面不会自动释放 i 所以跳出循环后 i 还是会再加1的,所以Msgbox i 应该等于 7
再问：也就是说Next就隐含了i=i+1对吗？
再答：没错,就是这样意思,你多试试就知道了另外,for i = 1 to 10 step 2 , 这才是for 循环的原型,step省略即+1而已, 如果step 2 跳出循环后 i 是再加2 的

for i = 1 to 3 Private Sub Command1_Click() For i = 1 To 3 For j = i To 1 a Private Sub Command1_Click() For i = 1 To 3 For j = 1 To i F for i=1 to 4 pascal For i:=1 to n a = 0 For i = 1 To 3 For j = 1 To i For k = j To 3 a = a + 1 为什么For i = 1 To 3 For j = 1 To i For k = j To 3 a = a + 1 Ne vb多重循环试题For i= 1 to 3 for j= 1to i for k= j to 3 a=a+1 next 有如下代码： For i = 1 To 3 For j = 1 To i For k = j To 3 a = a + 执行语句for i =1 to 3 i=i+1 next i 变量 i 的值是什么? Private Sub Command1_Click() n = 0 For i = 1 To 3 For j = -4 读下面程序：for i=1 to 3 for j=i to1 for k=j to 3 a=a+1 next k nex
