编写C程序，随机给出n*n的邻接矩阵，并打印输出邻接矩阵，以及有向图的边的个数，每个顶点的度，并判断该图中是否存在Euler回路： （1）如果为n阶，则随机产生一个n*n的邻接矩阵； （2）输出邻接矩阵，边的个数，每个顶点的度以及图中是否存在Euler回路。 这个题目涉及到了两个主要的知识点，一个是数据结构中的有向图的邻接矩阵的创建，还有就是离散数学中的Euler回路的判定定理。(The preparation of C procedures, were randomly given n* n s adjacency matrix and adjacency matrix printouts, as well as to map the number of edges, each vertex degrees, and determine the existence of the map Euler circuit: (1) If for n-order, then randomly generated a n* n adjacency matrix (2) output adjacency matrix, the number of edges, each vertex of degree as well as map the existence of Euler circuit. This topic relates to two main points of knowledge, a data structure of digraph adjacency matrix of creation, there is discrete mathematics in the loop to determine Euler theorem.)

有的科技图书会附有索引，其中列出书中重要术语出现的页码，便于读者查看。试设计一个类似的程序。输入是一个英文文本文件，输出是文件中关键字及其出现的行号的列表并按照关键字有序排列。程序运行方式：>index inputfile keys outputflie (Some books will be accompanied by technology index, which lists important terms appear in the book pages, easy to readers to view. Try to design a similar procedure. English text input is a file, the output is a file that appears in the keywords and their line numbers list and ordered according to keywords. Program run mode:> index inputfile keys outputflie)

PB的源码程序 8.0的列子 demo简单(pb sourcecode code)

Factory 模式的两个最重要的功能： 1）定义创建对象的接口，封装了对象的建； 2）使得具体化类的工作延迟到了子类中。 (Factory mode two most important functions: 1) the definition of an object to create an interface that encapsulates the construction objects 2) makes specific class work delayed to subclasses.)

这是vb编写的计算器的源代码，比较容易懂，比较实用(This is the preparation of the calculator vb source code, it was relatively easy to understand, more practical)
