C语言体育器材管理系统

好的，体育器材管理系统可以包括以下功能：

1. 添加器材：管理员可以添加新的器材，包括器材名称、数量、价格等信息。

2. 删除器材：管理员可以删除不需要的器材。

3. 修改器材：管理员可以修改器材的信息，包括名称、数量、价格等。

4. 查询器材：用户可以查询所需器材的信息，包括名称、数量、价格等。

5. 借出器材：用户可以借出所需的器材，并记录借出时间、归还时间等信息。

6. 归还器材：用户可以归还借出的器材，并更新器材的数量。

7. 统计器材：管理员可以统计器材的使用情况、库存情况等信息。

下面是一个简单的C语言体育器材管理系统的代码示例：

该系统主要通过结构体来存储器材和借出记录的信息，并提供了各种功能来管理和查询器材信息。可以根据实际需求对代码进行修改和完善。
