读取串口的源码
串行口是计算机一种常用的接口，具有连接线少，通讯简单，得到广泛的使用。常用的串口是 RS-232-C 接口（又称 EIA RS-232-C）它是在 1970 年由美国电子工业协会（EIA）联合贝尔系统、 调制解调器厂家及计算机终端生产厂家共同制定的用于串行通讯的标准。它的全名是"数据终端设备（DTE）和数据通讯设备（DCE）之间串行二进制数据交换接口技术标准"该标准规定采用一个 25 个脚的 DB25 连接器，对连接器的每个引脚的信号内容加以规定，还对各种信号的电平加以规定。传输距离在码元畸变小于 4% 的情况下，传输电缆长度应为 50 英尺。

DataGridViewAutoFilter
The Microsoft® Windows Forms DataGridView control in
Microsoft® Visual Studio® 2005 provides a grid experience similar to Microsoft®
Excel, but does not provide the column filtering drop-down lists that Excel
provides in its AutoFilter feature. However, the DataGridView can bind to data sources that provide
filtering, such as the ADO.NET DataView. This article describes how to build a custom DataGridView column header cell
that displays drop-down filter lists, by taking advantage of the filtering
capabilities of the data source and the new BindingSource component.

编写一程序，统计学生的成绩信息（保存在文件Score.dat中）。
要求：
1. 能按总分，数学成绩，英语成绩，计算机成绩分别排序
2. 能分别统计数学，英语，计算机中不及格人数
3. 能按学号查找学生，并显示该学生信息。
注
1. 从文件中读入数据以及功能菜单显示已在文件ReadData.c 和Menu.c中给出；
2. 代码的总体结构已在文件Score.c中给出，并定义了一些函数头，但有关函数体代码和一些主程序处理代码要求学生填写，也可以修改函数头；
编译score.c即可
-prepared a procedure, the results of the students statistical information (stored in the document Score.dat). Requirements : 1. According to score, the math and English results, the computer results were 2 ranking. Statistics were able to mathematics, English, Computer failure number three. can search by school, students, and that the student information. Note 1. Read from the file into the data and functions of the menu showed the documentary and Menu.c ReadData.c given; 2. The overall code structure has been the Score.c given, and the definition of some of the first function, However, the body function code and address some main program code requiring students to complete, can also modify function first; compiler can s

医院管理系统
这是一个有点长，但简单迷你项目在C编程语言。医院管理系统项目是一个控制台应用程序，没有建为 Code::Blocks 的图形。该项目利用文件处理有效，并会教你如何添加、 编辑、 使用文件的搜索和删除记录。这里提供的源代码是完整的、 无错误，并可以免费下载。设计为艾尔卡医院，坐落在尼泊尔勒利德布尔。
为源代码在 C 中的医院管理系统项目是超过 1100年线。所以，我选择不显示在这篇文章的源代码。您需要编译的源代码中 Code::Blocks 使用 GCC 编译器。你可以从下面的链接直接下载源代码和应用程序文件的这一项目。
