对以字符串输入的长度100以内的大整数进行乘法运算，结果也以字符串输出 例char *mulit1=“1234567890123456789012345678901234567890” char *mulit2=“12345678901234567890” 结果为：“15241578753238836750342935775034293577501905199875019052100” 长度为59

摘要 通信的目的是要把信息及时可靠地传送给对方，因此要求一个通信系统传输消息必须可靠与快速，在数字通信系统中可靠与快速往往是一对矛盾。为了解决可靠性，通信系统都采用了差错控制。本文详细介绍了循环冗余校验CRC（Cyclic Redundancy Check）的差错控制原理及其算法实现。 关键字 通信 循环冗余校验 CRC-32 CRC-16 CRC-4 概述 。。。。。

For those that do not know me: My name is Jacco Bikker, also known as 'Phantom'. I work as '3D tech guy' at Overloaded, a company that develops and distributes games for mobile phones. I specialize at 3D Symbian games, which require highly optimized fixed-point, non-HW-accelerated 3D engines, crammed into 250Kb installers. So basically I'm having fun. As software rendering used to be my spare time activity, I was looking for something else. I tried some AI, which was great fun, and recently I dove into a huge pile of research papers on raytracing and related topics; such as global illumination, image based lighting, photon maps and so on. One document especially grabbed my attention. It's titled: "State-of-the-Art in Interactive Ray Tracing", and was written by Wald & Slusallek. I highly recommend this paper. Basically, it summarizes recent efforts to improve the speed of raytracing, and adds a couple of tricks too. But it starts with a list of benefits of raytracing over rasterization-based algorithms. And one of those benefits is that when you go to extremes, raytracing is actually faster than rasterizing. And they prove it: Imagine a huge scene, consisting of, say, 50 million triangles. Toss it at a recent GeForce with enough memory to store all those triangles, and write down the frame rate. It will be in the vicinity of 2-5. If it isn't, double the triangle count. Now, raytrace the same scene. These guys report 8 frames per second on a dual PIII/800. Make that a quad PIII/800 and the speed doubles. Raytracing scales linearly with processing power, but only logarithmically with scene complexity. Now that I got your attention, I would like to move on to the intended contents of this crash course in raytracing.

在智能手机时代，每个品牌的手机都有自己的个性特点。正是依靠这种与众不同的个性来吸引用户，营造品牌凝聚力和用户忠城度，典型的代表非iphone莫属了。据统计，截止2011年5月，AppStore的应用软件数量达381062个，位居第一，而Android Market的应用软件数量达294738，紧随AppStore后面，并有望在8月份越过AppStore。随着Android系统逐步扩大市场占有率，终端设备的多样性亟需更多的移动开发人员的参与。据业内统计，Android研发人才缺口至少30万。目前，对Android人才需求一类是偏向硬件驱动的Android人才需求，一类是偏向软件应用的Androi
