C语言学习---小游戏---猜数字

void meun()
{
    printf("1.play");
    printf("2.exit");
}
void game()
{
   //随机数0-32726
    int ret = rand() %100+1;
    int guess = 0;
    while (1)
    {
        printf("number:");
        scanf("%d",&guess);
        if(guess < ret)
        {
            printf("minn");
        }else if(guess > ret)
        {
            printf("maxn");
        }else
        {
            printf("bingon");
            break;
        }
    }
}
int  main()
{
    srand((unsigned int)time(NULL));//传入时间戳
    int input = 0;
    do
    {
        meun();
        scanf("%d",&input);
        switch (input)
        {
        case 1:
            game();
            break;
        case 2:
            printf("exit");
            break;
        default:
            printf("fail");
        }
    }
    while (input);


    return 0;

}

实现功能：产生随机数，选择1继续，猜的数字大于或者小于均有提示。猜到数字bingo。退出按2
