数据结构中关于十字链表的实现，十字链表可以很好的对稀疏矩阵进行效率很高的存储和计算。比如在通信纠错编码的ldpc编译码中就要用到这种数据结构-data structure on the realization of Chain Cross, Cross List can be good for sparse matrix highly efficient storage and computing. For example, in communications-correction coding ldpc encryption it is necessary to use this data structure

java 数据结构与算法译作者： [美]Clifford A.Shaffer著 张铭 刘晓丹译 　　包含范围：Java算法 　　尽管基本上Java图书都是讲Java本身的特性。因为Java的体系太庞大了，而用Java来实现的数据结构与算法，这本书也是唯一一本，所以尽管这本不是那么的好但还是做以推荐 -java construction of data and algorithm translated work: [ Is beautiful ] Clifford A.Shaffer inscription Liu Xiao Dan to translate Contains the scope: Java algorithm Although the basically Java books all speak the Java itself characteristic. Because of Java system too huge, but construction of data and algorithm which realizes with Java, this book also is only 11, therefore although this originally is not such is good but or does recommends

用VB6创建的家庭地址簿程序。制作该程序的主要目的是用来为家庭中的每个成员存储个人地址信息。而且该程序的用户设定为两个类型级别：即1管理型、2用户型-built with VB6 family address book procedures. The production process is the main purpose for the family members of each of the addresses stored personal information. And the procedures set of users for the two types of levels : that is a management-type, two-users
