大型数据库，最基本的PL/SQL语句，及其基础编程。-Large databases, the basic PL/SQL statement, and its basic programming.

使用两个向量的叉积来判断两条线段是否相交-The use of the cross product of two vectors to determine whether two line segments intersect

OCI（Oracle Call Interface）是ORACLE公司开发的一个应用程序开发工具，是一个通过访问Oracle数据库的服务器，控制各类SQL语句的执行，进而创建应用程序的的应用程序接口（API）。它支持SQL所有的数据定义，数据操作，查询，事务管理等操作，支持C和C++的数据类型，调用，语法和语义。它提供了一组可对Oracle数据库进行存取的接口子例程(函数)。 OCI程序实质上就是用高级语言写的程序，其特点是内部含有对OCI子函数库的调用，通过在第三代程序设计语言(如C语言)中进行调用可达到存取ORACLE数据库的目的。 本工程包含一个简单的oci封装，封装oci的基本操作，日常开发中对速度要求比较高而ado和普通的odbc方法满足不了要求的情况下可以考虑使用-OCI (Oracle Call Interface) was developed by an ORACLE application development tool, one by accessing the Oracle database server and control the implementation of various types of SQL statements, thereby creating the application s application program interface (API). It supports all SQL data definition, data manipulation, query, transaction management, operation, support C and C++, data types, call, syntax and semantics. It provides a set of Oracle database can access the interface sub-routines (functions). OCI program in essence is to use high-level language to write programs, characterized by an internal subroutine library that con

快速排序的非递归算法,具有高效的特点，快速排序 -the nonrecursive code of quicksort

主要是二叉树的一些性质的操作。包括复制，清空，求取树高，树中元素的个数，得到根结点，父亲结点，所有祖先，左儿子，右儿子，插入左儿子，右儿子，查找某个元素，以及前、中、后、层次遍历和相关的操作。另外，可以树形显示这棵树的信息。-Some properties are mainly binary operation. Including reproduction, empty, to strike a tree height, the number of elements in the tree get root node, the father node, all the ancestors, the left son, right son, insert the left son, right son, to find an element, and the former , during and after, hierarchical traversal and related operations. In addition, you can display tree tree information.
