《c语言入门经典》第四章最后simon游戏程序问题

c语言入门经典第四版这本书中第四章最后的范例是个simon游戏，要求计算机屏
幕上显示一串数字显示很短时间。玩家需在数字消失前记住他们。
但是我照书上敲了代码，可游戏开始就是显示不了数字呀，是不是随机数rand()那里有问题？请大神帮忙看下下面的代码：
#include
#include
#include
#include
#include

int main()
{
char another_game = 'Y';定义不止一次游戏
bool correct = true;定义猜对序列
int counter = 0;游戏次数统计
int sequence_length = 0;序列的数字长度
int seed = 0;rand随机数种子
int number = 0;初始化输入的数字
long now = 0;计时器
int time_taken = 0;用时
int i =1;

printf("\n To play simple simon, ");
printf("watch the screen for a sequence of digits.");
printf("\n Watch carefully, as the digits are only displayed

for second!");
printf("\n The computer will remove them, and then prompt

you");
printf("to enter the same sequence.");
printf("\n When you do, you must put spaces between the

digits.\n");
printf("\n Good luck!\npress enter to play\n");
scanf("%c", &another_game);

do
{
    correct = true;
    counter = 0;
    sequence_length = 2;
    time_taken = clock();


    while(correct)
        {
            sequence_length += counter++%3 ==0;
            seed = time(NULL);

            now = clock();

            srand((unsigned int)seed);
            for(i = 1; i <= sequence_length; i++)
                printf("%d", rand() % 10);

            for( ; clock() - now < CLOCKS_PER_SEC;

);
printf("\r");

            for(i = 1; i <= sequence_length; i++)
                printf(" ");

            if(counter == 1)
                printf("\n Now you enter the

sequence - do not forget the spaces\n");
else
printf("\r");
srand((unsigned int)seed);

            for(i =1; i <= sequence_length; i++)
            {
                scanf("%d", &number);
                if(number != rand() % 10)
                {
                    correct = false;
                    break;
                }

            }
            printf("%s\n", correct ? "Correct!" :

"Wrong!");
}

        time_taken = (clock() - time_taken) /

CLOCKS_PER_SEC;

        printf("\n\n Your score is %d", --counter *

100 / time_taken);

        fflush(stdin);

    printf("\n Do you want to play again (y/n)? ");
    scanf("%c", &another_game);
} while(toupper(another_game) == 'Y');


return 0;

}
不胜感激。。

seed没见你打印显示出来

LZ没有注意到这个语句：你再去好好看看你的代码的逻辑；程序没有错，开始运行后你应该输入‘Y’字符；才能开始游戏。

 scanf("%c", &another_game);
