RT，编译之后只能运行一次，到了应该输入y或者n的时候程序就自动退出了！跪求解答！


#include <stdio.h>
#include <stdlib.h>

int main(void)
{
    char another_game='y';
    printf("Hay man!If you wanna try this,press ENTER!\n");
    scanf("%c",&another_game);
    while(another_game=='y');
    {
        int num1=0,num2=0;
        num1=1+rand()%10;
        printf("Look,all you need to do is type a number from 1~10,and press ENTER.Quite simple,uh?Good luck!\n");
        scanf("%d",&num2);
        if(num2==num1)
        printf("You are doing so well!\n");
        else
        printf("Well,maybe you will be lucky next time\n");
        printf("Another round?y/n");
        scanf("%c",&another_game);
      }

   return 0;
}

多谢！现在可以用了！
另外想请问一下为什么 scanf("%*c");也可以清除缓冲区？%*c是什么格式符？

回6L~谢谢~
