丰哲琬15064945001 ______ 有影响的啊 输出结果是 1 3 5 7 如果侧掉 K = K + 2 则输出只有 1,无变化 Private Sub Command1_Click() For i = 1 To 4 '循环四次,即 1 ~ 4 b = k + 1 '对变量 b 赋值 Print b '将变量 b 的值 输出到窗体上 k = k + 2 '对变量 K 赋值 Next '循环结束 End ...
仰菊固2109VB程序的循环结构,计算程序
丰哲琬15064945001 ______ 结果是: 4 7 10 for 语句设置的i的步长为2,当i=2时,x=x+3即x=1+3=4,将此值打印出来,Next i后,i的值为4,此时x=x+3=4+3=7,再将此值打印出来,再次Next i后,i的值变为6,再次执行x=x+3=7+3=10,最后再将值打印出来,当再次next i时,i的值已经编程8不满足 For语句的条件,i的值小于等于6的条件,所以退出For循环.
