关于这个 while 为何会循环打印 2 次
程序代码：#include<stdio.h>
int main(void)
{
int guess=1;
printf("Uh..is your number %d?\n",guess);
while(getchar()!='y')
printf("Well,then,is it %d?\n",guess++);
printf("i konw i could do it\n");
return 0;
}首先打印Uh..is your number 1
然后要求输入，如果等于Y，打印i konw i could do it
如果等于N，打印Well,then,is it %d?
假如如下
Uh..is your number 1?
键入n
Well,then,is it 2?
n
Well,then,is it 3?
y
i konw i could do it
这个是预期结果，可是为什么每次输入N后就连续打印2次
Well,then,is it 2?
Well,then,is it 3?
n
Well,then,is it 4?
Well,then,is it 5?
