想用二维数组打印字符串，不知道二维数组怎么用。

#define YES 1

char str[30]={"就被你猜中了！"};
char str1[30]={"才猜中答案！"};
char str2[30]={"看来你的IQ很低！"};
char fall[30]={"请重新输入！"};
int main()
{
    int guess_value=-1;
    int number;
    int nbr_of_guesses;
    int done=NO;

    srand((unsigned)time(NULL));
    number=rand();

    nbr_of_guesses=0;
    while(done=YES)
    {
        //printf("\n随机数是%d",number);//作弊码。
        printf("\n选一个0到%d的数字:",RAND_MAX);
        scanf("%d",&guess_value);
        nbr_of_guesses++;
        if(number==guess_value)
        {
        printf("\n太厉害了！居然被你猜中了。");
        goto AAA;
        }

    }
    AAA:if(nbr_of_guesses<=3)
    {
    printf("\n你猜了%d次,%s",nbr_of_guesses,str);
