[软件工程] 一元多项式计算器
(1)建立含有若干个元素的带表头的单链表；
要求从键盘输入和文件读入两个多项式，显示并保存。
（2）设有一元多项式Am(x)和Bn(x).
Am(x)=A0+A1x1+A2x2+A3x3+...+Amxm
Bn(x)=B0+B1x1+B2x2+B3x3+...+Bnxn
请实现求M(x)=Am(x)+Bn(x)、M(x)=Am(x)-Bn(x)、M(x)=Am(x)×Bn(x)以及计算M(x)=0的根，计算多项式在x处的值，求多项式M的导函数M，并将结果保存在文本文件中。
（3）多项式的输出形式为类数学表达式。例如，多项式-3x8+6x3-18的输出形式为-3x^8+6x^3-18，x15+(-8)x7-14的输出形式为x^15+8x^7-14。注意，数值为1的非零次项的输出形式中略去系数1，如项1x8的输出形式为x8，项-1x3的输出形式为-x3。
(1)A single linked list with a number of elements is set up.
Requirements from keyboard input and file read two polynomials, display and save.
(2) there are one polynomial Am (x) and Bn (x).
Am (x) =A0+A1x1+A2x2+A3x3+... +Amxm
Bn (x) =B0+B1x1+B2x2+B3x3+... +Bnxn
M (x) =Am (x) +Bn (x), M (x) =Am (x) -Bn (x), M (x), and calculated polynomials are calculated, and the derivative of polynomial is calculated and the results are saved in the text file.
(3) the output form of polynomials is a class of mathematical expressions. For example, the output form of polynomial -3x8+6x3-18 is -3x^8+6x^3-18, and the output form of x15+ (-8) x7-14 is x^15+8x^7-14. Note that the coefficient of 1 in the output form of the nonzero term with a value of 1 is equal to 1, for example, the output form of item 1x8 is X8, and the output form of item -1x3 is -x3.

[软件工程] 97Things
这是一本关于Refactoring的书，从网上搜集并且整理为PDF文档，希望大家可以从这篇文章中学到更多的东西。
In this truly unique technical book, today s leading software architects present valuable principles on key development issues that go way beyond technology. More than four dozen architects-- including Neal Ford, Michael Nygard, and Bill de h ra-- offer advice for communicating with stakeholders, eliminating complexity, empowering developers, and many more practical lessons they ve learned from years of experience. Among the 97 principles in this book, you ll find useful advice such as:
* Don t Put Your Resume Ahead of the Requirements (Nitin Borwankar)
* Chances Are, Your Biggest Problem Isn t Technical (Mark Ramm)
* Communication Is King Clarity and Leadership, Its Humble Servants (Mark Richards)
* Simplicity Before Generality, Use Before Reuse (Kevlin Henney)
* For the End User, the Interface Is the System (Vinayak Hegde)
* It s Never Too Early to Think About Performance (Rebecca Parsons) (2009-11-10, Visual C++, 318KB, 下载3次)
