回溯算法中的连续邮资问题-backtracking algorithms for the problem of postage

一个皮萨店的源码。可以连锁的，而且有各种口味的选择。-A pizza shop source. Can be linked and that there are different flavors.

功能：多线程、E-mail转发、自动隐藏，huffman、JPEG压缩，全屏、指定区域或最前窗口抓图，窗口或全屏控制方式，彩色或黑白显示，修改注册表、取密码、记录键盘信息等等。 缺点：控制端在WIN98下运行，每抓一幅图会吃掉几十K内存，不知道为什么，在WIN2000下运行没有发现这种情况，知道原因请通知我。E-mail:KelvinSpace@21cn.com Regedit:HKEY_CURRENT_CONFIG/CtrlSrvr设置E-MAIL地址等，电邮密码写在程序中（TVB） 服务端密码：TVB123(注意大小写) 文件：pe2.part01.rar至pe2.part05rar共5个文件 -Features: multi-threaded, E-mail forwarding, auto-hide, huffman, JPEG compression, full screen, specify the area or the front window, drawings, window or full-screen control mode, color or black and white display, modify the registry, get your password, record keyboard information and so on. Drawback: controlling end of the run WIN98, each grasping a plan would eat up tens of K of memory, do not know why, in the running under WIN2000 did not find such a situation, know the reason please let me know.

(1) 设计一个程序，用于根据用户输入的命令行参数数量来计算长方形、正方形、三角形的面积。如果输入的参数为一个、二个、三个则它们应分别对应正方形、长方形、三角形，如果没有参数，则通过异常处理方法现实错误消息。（用于计算面积的方法是一个重载的方法。提示：定义一个抽象的父类，并提供一个抽象的方法area(). 再派生出三个子类，重写area()方法，然后在main方法中用多态来实现具体的面积函数的调用）。-(1) design a program based on user input for the command line parameters to calculate the number of rectangular, square, triangle area. If the input parameter is one, two, three then they should correspond to a square, rectangle, triangle, without parameters, exception handling through the real error message. (Used to calculate the area is an overloaded method. Note: the definition of an abstract parent class, and provides an abstract method area (). To send birth to three sub-classes override area () method, and then in main method using multi-state to achieve a specific area of a function call).

这里实现跑马灯的方法是，依次灭掉前一个灯和点亮后一个灯，再延时一会，不断循环，就可以看到跑马灯的效果了。 请在编译后，进入仿真，点全速运行看结果-Marquee realize here the approach is to eliminate the former followed by a light and lit a lamp post, and then one will be delayed, and constantly cycle, you can see the effect of the Marquee. Please compiled into the simulation, watch the results point to run at full speed
