#include "stdio.h"
void main()
{
    char ch;
    while (1)
    {
        printf("Do you want to continue,press 'Y' or 'N' to chioce\n");
        ch=getchar();
        if (ch=='Y'||ch=='y')
            continue;
        if (ch=='N'||ch=='n')
            break;
    }
}

为什么ch为y时，printf出两行"Do you want to continue,press 'Y' or 'N' to chioce\n"？
不解，望大大回答~

谢谢了，各位
总算搞定了
