飞机订票系统 　　录入： 　　可以录入航班情况（数据可以存储在一个数据文件中，数据结构、具体数据自定） 　　查询： 　　可以查询某个航线的情况（如，输入航班号，查询起降时间，起飞抵达城市，航班票价，票价折扣，确定航班是否满仓）； 　　可以输入起飞抵达城市，查询飞机航班情况； 　　订票：（订票情况可以存在一个数据文件中，结构自己设定） 　　可以订票，如果该航班已经无票，可以提供相关可选择航班； 　　退票： 可退票，退票后修改相关数据文件 -Aircraft booking system (limited to 1 completed) Tasks: The system can be achieved through the following functions: Entry: Can be input flight conditions (data can be stored in a data file, data structure, specific data from set) Inquiries: Can query a particular route (such as, enter the flight number, check arrival and departure times, arrival departure city, flight fares, fare discounts, to determine whether the full flight position) Can enter the take-off on arrival, check flight situation Booking: (booking conditions can exist in a data file, structure their own set) Could be booking, if the flight has been without a ticket, you can provide alternative flights Refund: You can refund, a refund after the revision of re

DirectX Lighting vs. Real World Lighting （DX光照 对 真实世界光照） 在DX中，我们能创建不同类型的光，使场景看起来更真实。但要记住，DX中的光只是在近似地模拟自然界的光。在自然界中，光由光源（如灯泡）发出，然后延直线传播，直到消耗完毕或传入眼睛；光在遇到物体时会发生反射，每次反射都会有能量的消耗；实际上，光可以在物体间反射千百万次，而且光滑表面会比不光滑的表面反射更多的光。这一切如果全算进来的话，计算量是巨大的，所以，DX只是在近似地模仿。 -DirectX Lighting vs. Real World Lighting (DX light illumination of the real world) in the DX, we can create different types of light, to make scenes look more realistic. Bear in mind, however, DX in the light only in the approximation to simulate natural light. In nature, light from light source (such as light bulbs) to issue, and then the extension of a straight line, until the consumption of finished or imported into the eyes-ray object in the face of reflection will occur, each reflection will have energy consumption in fact, light can be inter-reflection in the object of millions of times, and the smooth surface than the non-smooth surface reflects more light. All full-count in. If so, computation is enormous, so, DX only approximate
