走过路过的看看吧！
在TC中运行了！为什么只对第一个数进行查找！错了！帮改改改吧！先谢了！

排序排错了！

哥们实在不好意思
我大意了
这次应该没问题了

{
return 1;
}
else if(k <a[mid])
{
high=mid-1;
}
else
{
low=mid+1;
}
}
return 0;
}
int main(void)
{
int a[100];
int p,k,max;
int i, j, temp;
p = 0;
printf( "MAX: ");
scanf( "%d ",&max);
srand((unsigned)time(NULL));
/* 产生max个随机数 */
for(i=1; i <=max; i++)
{
a[i] = rand();

{

{
temp = a[i];
a[i] = a[j];
a[j] = temp;
}
}
}
/* 从小到大的顺序排列 */
for (i=1; i <=max; i++)
{
printf ( "%-10d ", a[i]);
}
printf ( "\n ");
printf( "\nK: ");
scanf( "%d ",&k);
p=Seq_search(a, k, max);
if(p==1)
{
