这是非常有挑战性的题目。对于用户输入的任意一个平面函数f(x)，绘制出其函数曲线。这里最关键的技术难点就是如何实现计算表达式的值。在《编译原理》和《数据结构》的书中，都有对表达式运算方法的论述。说实在的，在编译型计算机语言中实现对用户输入表达式的运算是非常困难的。需要对表达式进行扫描，去括号，按照运算符的优先级生成2叉树，然后遍历该树生成逆波兰表达式，再然后通过栈的方法进行运算。如果在表达式中再包含有函数的话......描述起来都麻烦，更不要说用程序实现了:-(-This is a very challenging issue. For user input an arbitrary planar function f (x), mapping out its function curves. Here the most critical technical problems is how to achieve calculated the value of the expression. "Compiling Principle" and "data structure," the book, have right of expression Operational discussed. Indeed, the computer language compiler to achieve expression of the user input operation is very difficult. Need to scan expression to the brackets, in accordance with the priority Operators Generation 2-ary tree, and then traverse the tree generated reverse Polish expression, and then through the stack approach to computing. If the expression again contains the function described ...... these are trouble, not to mention t

VC实现基于串口通讯的食堂饭卡系统,需要和相应的硬件结合实现.废话不多说了,大家下载吧,呵呵,给点评价哦!-VC based serial communications canteens Fanka system, needs and corresponding hardware combination to achieve. nonsense, said little, we downloaded it, huh, to the point evaluation Oh!

一个很好的串口监视程序，可以实现串口发送数据的监视-A very good serial surveillance procedures, can send data to serial surveillance

可以完成CRC的校验功能,提供16为的循环冗余校验-it can support the check of CRC

一个功能完全的串口读写程序，里面实现的串口读写类可以方便的复用。-a fully functional literacy Serial procedures inside the serial achieve literacy classes can facilitate the reuse.

这是一个红外温度探头测试程序，用于对温度探头进行测试，同时也可以作为温度采集用。由于探头通过RS232与计算机连接，所以程序包括串口通信的实现，串口通信利用了第三方通信类CSerial。程序可以将测得的数据保存为Excel文档。-This is an infrared temperature probe testing procedures used to test the temperature probe, but also used as temperature acquisition. As the probe through RS232 connection with the computer, including procedures for the realization of serial communications, serial communications using a third-party communications category CSerial. Procedures can be measured data to Excel document preservation.
