试按以下要求编写洗牌模拟函数。令52张牌按顺序排序于0~51对应。首先顺序地将花色和面值天如数组deck中，然后逐一考察这52张牌，并为每一张牌随机产生一个0~51的一个数字。并将当前正在考察的牌于随机产生的整数对应的牌对换。直至每张牌都被考察后停止洗牌。
怎么样控制随机数的范围呢？

rand()%n
将产生0-(n-1)的随机数

可以把代码写一下吗？我在下面调了很久没有弄好
谢谢

把你的代码发出来看看

{
char *deck[52][2];
int temp[52],i,j,tem;
for(i=0;i<52;i++)
temp[i]=i;
srand(time(NULL));
for(i=0;i<52;i++)
{
tem=rand()%(52-i);
j=temp[52-i-1];
temp[52-i-1]=temp[tem];
temp[tem]=j;
}
for(i=0;i<52;i++)
{
deck[i][0]=suit[temp[i]/13];
deck[i][1]=face[temp[i]%13];
}
for(i=0;i<52;i++)
{
if(i%13==0)
printf("\nPlay %d: ",i/13+1);
printf("%s %s ",deck[i][0],deck[i][1]);
}
printf("\n");
return 0;
}

大家看下我做的.不知道有错误没..做的我头疼..

srand(time(NULL));
这句话是什么意思
----------------解决方案--------------------------------------------------------
deck[i][0]=suit[temp[i]/13];
为什么不是deck[i][0]=suit[temp[i]％4];呢
----------------解决方案--------------------------------------------------------
deck[i][0]=suit[temp[i]/13];
为什么不是deck[i][0]=suit[temp[i]％4];呢
srand(time(NULL));这个是为随机数产生种子.
temp[i]存放的是0-51的数,他们分别代表一张牌.
我们可以规定0-12对应红桃
13-25对应...
