题目：取一个整数a从右端开始的4～7位。 程序分析：可以这样考虑： (1)先使a右移4位。 (2)设置一个低4位全为1,其余全为0的数。可用~(~0<<4) (3)将上面二者进行&运算。 2.程序源代码：(Topic: take an integer a from the right end of the four to seven began. Program analysis: it can be to consider: (1) to make a move to the right four. (2) sets a low four total for the 1, all the rest for 0 of the number. Can be used to (~ 0 < < 4) (3) will above the difference and operations. 2. The source code:)

一个标准的MFC Windows应用程序 要求：1、创建一个单/多文档的MFC程序，使其具有自定义的菜单、工具栏和状态栏。 2、菜单和工具栏的功能自定义。 3、应用程序的背景是一幅位图图片。 4、工具栏应该可以显示和隐藏，而且它有一个菜单不具有的功能。 (A standard MFC Windows application requirements: 1, to create a single/multi-MFC documentation procedures, so that it will have custom menus, toolbars, and status bar. 2, menus and toolbars custom functions. 3, the application of the background is a bitmap image. 4, the Toolbar should be able to show and hide, and it does not have a menu function.)

枚举驱动列表，获取驱动的设备句柄 这是Win7上常用的获取设备句柄的方法。 我在原代码的基础上，添加了SetupDiEnumDeviceInterfaces 来获取驱动的详细信息。(SetupDiEnumDeviceInterfaces SetupDiGetClassDevs SetupDiEnumDeviceInterfaces)

电子标签防碰撞是RFID 系统中一个关键问题。在射频识别系统中．当阅读器作用范围内有多个标签同时向阅读器发送数据时，会产生冲突，必须采用一种防碰撞算法解决这种冲突。在分析典型的二进制及动态二进制防碰撞算法基础上，采用了一种新的防碰撞算法。经实验证明，该算法能有效解决射频识别系统中多目标识别的防碰撞问题。(Tag anti-collision RFID system is a key issue. In the radio frequency identification systems. When the reader within the framework of the role of multiple tags simultaneously send data to the reader, it will create conflict, you must use a anti-collision algorithm to solve such conflicts. In the analysis of a typical binary and dynamic anti-collision algorithm based on the binary, using a new anti-collision algorithm. The experiments show that the algorithm can effectively solve the radio frequency identification system, multi-target recognition of the anti-collision problem.)
