自动搜索光盘，查找多媒体文件，生成播放列表，并自动播放，特别是支持大多数加密光盘 密码光盘(automatically search CD-ROM search multimedia files, generate a playlist and played automatically. particularly in support of the majority of password encryption CD discs)

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)

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.)

这是C++Primer的书籍的源代码，包括课后习题的答案，是份很不错的代码，尤其针对初学者(This is the source code of C++Primer books, including after-school exercises, answers, were very good code, especially for beginners)

说明：  

16进制如何转化为10进制的，进制转换是需要注意什么，怎么样会更简单(0x d)

说明：  vs2015编程，图书馆管理系统，界面登录，借书系统。连接了数据库（SQL SERVER2014)。还书系统，超期罚款等等(Vs2015 programming, library management system, interface login, library system. Connected to the (SQL SERVER2014). Book system, overdue fine and so on)
