程序代码：

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


int main(void)
{
    int Roll_Count, mest, play;//mest是检测循环是否运行，play是玩家输入数值
    mest = 1;


    srand(time(0));

     printf("猜数字游戏开始！\n");
    while (mest > 0)
    {
        scanf("%d", play);
        if (play == Roll_Count)//判断是否正确
        {
            printf("恭喜你获得胜利！猜对"
                   "了！答案就是%d!\n", play);

        }
        else
        {
            if (play < Roll_Count)//判断是太大还是太小
            {
                printf("您输入的数%d太小，请"
                       "重新输入！/n", play);
            }
            else
