说明: 设计模式一(单子、工厂、策略模式)练习
1. 假设现在要设计一个贩卖各类书籍的电子商务网站的购物车系统。对所有的教材类图书 实行每本一元的折扣;对连环画类图书提供每本7%的促销折扣;而对非教材类的计算机图书有3%的折扣;对其余书没有折扣。使用策略模式、工厂模式、单子模式进行设计(Design Mode 1 (List, Factory, Strategy Mode) Exercise
1. Suppose we are going to design a shopping cart system for e-commerce websites that sell all kinds of books. All textbook books are discounted at one yuan per book; comic books are discounted at 7% per book; computer books are discounted at 3% for non-textbook books; and other books are discounted at no rate. Design using strategy mode, factory mode and single mode)

时钟 走动
说明: 一个应用线程实现指针运动的指针时钟程序。程序应用绘制函数时钟面板,根据线程休眠时间间隔,每隔1000ms进行一次重绘。程序通过获取系统时间函数并加以计算个指针位置,再利用绘制函数将其绘制在面板上,通过设置指针长度及颜色,实现时针、分针、秒针的区分。次外,通过获取窗体大小,设置圆面圆心坐标及半径,可依据窗口大小动态划分圆面大小,并动态绘制刻度点位置。(A pointer clock program that uses threads to implement pointer movement. The program draws the function clock panel and redraws it every 1000ms according to the interval of thread dormancy. The program obtains the system time function and calculates the position of a pointer, then draws it on the panel by drawing function. By setting the length and color of the pointer, it achieves the distinction of clockwise, minute and secondhand. Secondly, by acquiring the size of the form and setting the coordinates and radius of the circle center, the circle size can be dynamically divided according to the size of the window, and the location of the scale points can be dynamically plotted.)

说明: LL(1)文法和预测分析方法
1.文法使用产生式来定义;
2.分别求出文法中每一个非终结符的FIRST集、FOLLOW集和SELECT集;
3.画出预测分析表;
4.判定给定的文法是否是LL(1)文法;
5.给定符号串判定是否是文法中的句子,分析过程用分析表格的方式打印出来。(LL(1) Grammar and Predictive Analysis
1. Grammar is defined by production.
2. Find out the FIRST set, FOLLOW set and SELECT set of each non-terminator in grammar.
3. Draw a forecast analysis table.
4. Determine whether a given grammar is LL(1) grammar;
5. Given a string of symbols to determine whether it is a sentence in grammar, the analysis process is printed out in the form of an analysis table.)
