这是一款非常实用的计算器,我认为其实用程度远远胜过Windows系统提供的计算器.主要特色是支持多项式运算,即可以一次输入整个多项式,并能够识别运算的优先级(利用堆栈实现),希望大家能够多提宝贵意见.(This is a very useful calculator, I think in fact much better than using Windows system calculator. The main feature is support for polynomial computing, that is, can enter an entire polynomial, and to identify the priority operator class (using the stack realize), hope that we can with more valuable advice.)

在网上搜索到的很早的大宝兄的代码，写的还是满不错的，多采用List实现。希望对大家开发有所帮助。-Online english to early Dabao brother of code, written in full or good use List realize. Would like to help everyone develop.

vc作图，已画好的红框随着鼠标的移动而移动，当鼠标点击后，红框停在鼠标点击的位置后再变化(vc mapping, has drawn a good red frame and moves with the mouse when the mouse click, mouse click to stop the red line and then change position)

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:)
