大一c语言，头又秃了
这是一个学校羽毛球场的预约系统。该羽毛球场共有8片场地，基本预约单元为一个小时。周一到周五下午3点到9点（除去周一、三、五下午5点到8点为教工羽协活动时间不可）可预约，周六日上午9点到下午9点均可预约。时间可直接从电脑获取。不要所有场地都是空的，随机安排一些场地已经被预约了。
遇到的问题是下图，无法显示今天的场地信息，可预约时间也没有按要求显示，猜测可能是void generate_court_availability() 和print_court_availability（）出了问题
另外希望能加上过了时间就不能预订之前的场地的功能

从你给的图看，你的程序需要做成手机app的，这个用C语言基本上也做不了啊。怎么说，你也得用Java或者Swift之类的做，而且要有一个后台。
否则所有人在一个电脑上完成预约么
意思是控制台输出也行是吗
- 这个问题的回答你可以参考下: https://ask.csdn.net/questions/7544255
- 除此之外, 这篇博客: C语言实现八大排序算法详解及其性能之间的中的 这里需要对堆有一定的了解，堆就是一个比较特殊的完全二叉树，在最大堆里，每个节点的值都大于其左右两个孩子节点的值。这就是最大堆。反之就是最小堆。拿最大堆举例子，每次堆顶的元素值，不就是当前数列的最大吗？这不就成选择排序里的简单排序了吗？找完之后，将他和完全二叉树里最后一个结点的值进行交换，然后做一个自顶向下的自我调整，将他再次调整成一个完全二叉堆。第二次取最大的树，这时我们需要将上一次找到的结点屏蔽掉，不然会陷入一个死循环。无数次找完之后，再按层序的思想将二叉树里的数据遍历到一个数组当中，这时的数组为一个有序的数组。 部分也许能够解决你的问题, 你可以仔细阅读以下内容或跳转源博客中阅读:

该代码使用结构体和数组来存储预约信息，并在预约时检查场地的可用性和时间限制。将预约信息保存在文件中，下次运行程序时可以加载之前的预约信息。通过使用菜单选择，用户可以登录账号、录入预约人员信息、预约场地、查询信息和取消预约等操作。
请注意，这只是一个简单的示例代码，可能还需要根据实际需求进行一些修改和完善。例如，可以添加错误处理、输入验证和其他功能来提高系统的稳定性和用户体验。
