飞机订票退票系统 模拟一个飞机订票退票系统 假定某民航机场有m个航班，每个航班都只到达一个目的地。试为该机场售票处设计一个自动订票和退票系统。 要求系统具有以下功能： （1）订票。若该航次余票数大于等于乘客订票数，则在该航次的乘客表（按乘客姓氏字母顺序连接）中，插入订票乘客的信息项，并修改该航次的有关数据，否则，给出相应的提示信息。 （2）退票。若该航次余票数小于等于乘客订票数，则在该航次的乘客表中找出该乘客项，修改该航次及乘客表中有关数据。当由于退票，使得该乘客的订票数为零时，要从乘客表中撤消该乘客项；否则，给出相应的提示信息。 （3）、将某航次的余票数恢复初值――该航次的最大客票数。 当客户订票数要求不能满足时，系统也可向客户提供到达同一目的地的其他航线情况。

FCM算法是一种基于划分的聚类算法，它的思想就是使得被划分到同一簇的对象之间相似度最大，而不同簇之间的相似度最小。模糊C均值算法是普通C均值算法的改进，普通C均值算法对于数据的划分是硬性的，而FCM则是一种柔性的模糊划分。在介绍FCM具体算法之前我们先介绍一些模糊集合的基本知识。-FCM algorithm is a clustering algorithm based on the division of its thinking is that it is making is divided into clusters with the greatest similarity between the object, and different similarity between the smallest cluster. Fuzzy C-means algorithm is an ordinary C-means algorithm, the general C-means algorithm for data delineation is rigid, while the FCM is a soft fuzzy partition. FCM in the introduction prior to the specific algorithm we first introduce some basic knowledge of fuzzy sets.

《COM应用程序框架》是把标准的Microsoft Windows多文档处理应用程序使用COM技术来设计，这是文章的配套代码。 -"COM application framework" is the standard Microsoft Windows Multi- Document Service Jimmy applications that use COM technology to design, which is supporting the article code.

这些都是适合初学者的经典例子，初学不需要太难的程序，简单易懂的更能帮助学习C++的起步-some classic examples to help new hands to learn C++

针对助推- 滑翔导弹的弹道优化问题,给出了一种求解其最大射程弹道的分段优化方法,建立了其 纵平面运动模型和弹道优化模型。在考虑攻角绝对值、攻角变化率、法向过载、分离点攻角衔接及落地条件等约束 下,应用序列二次规划法求解了其最大射程弹道。分析表明,助推- 滑翔导弹比传统弹道导弹射程显著提高,其最 优弹道的起伏有助于增大射程和提高突防能力-For booster- Optimize glider ballistic missile problem, give a maximum range of its ballistic solution of the sub-optimization method, set up the vertical plane motion model and optimization model of trajectory. In considering the absolute angle of attack, the rate of change of angle of attack, normal load, the separation point of convergence and the arrival angle of attack constraint conditions, the application of sequential quadratic programming method to solve a maximum range of its ballistic. Analysis showed that propelled- gliding range ballistic missile than the traditional significantly improve, the optimal trajectory of the ups and downs will help increase the range and ability to enhance penetration
