在c++中 对于异常处理有不同的方法，而这个ppt主要讲述的怎么从第一步开始处理异常，异常的捕获和异常的继承，内容比较齐全

说明：  给定n种物品和一个背包,物品i的重量是Wi,价值是vi,被包容量是C,应该如何选择装入被包的物品,使得装入背包中物品的总价值最大?对于每种物品i,只有两种选择,装入或者不装入. 输入:第一行两个正整数n(物品数)和C(容量) 第二行n个正整数n,表示物品价值 第三行n个正整数n,表示物品重量 输出:第一行表示总价值 第二行n个数(0/1),0表示物品不装入,1表示装入 例如, 输入: 5 10 6 3 5 4 6 2 2 6 5 4 输出 15 1 1 0 0 1 (Species of a given n items and a backpack, the weight of item i is Wi, the value of vi, was packet capacity is C, should be how to choose a package of items to be loaded, the backpack load in the largest total value of goods? For each item i, there are only two options, loaded or not loaded. Input: the first line of the two positive integer n (the number of items) and C (capacity) of the second line of n positive integer n, that the value of the third line of n positive integer n, that the weight of output: the total value of the first line of the second line, said n number of (0/1), 0 that the items do not load, that load 1 for example, enter: 5,106,354,622 6 5 4 output 15 1 1 0 0 1)

发现usb_hid网上可参考的资源少，基于C#源码的就更少了，尤其是能通过验证的资源简直是没有，本usb hid源码在两三个银行用外部标准接口的硬件设备（如柜外清，条码识别，及指纹识别）测试通过了，关键是已经封装成了一个C#控件，使用时只需调用UsbLibrary.dll文件就行了，别再用那writefile了(Found usb_hid fewer resources available online reference, based on C# source code and even less, especially through the resources simply do not verify the source usb hid in two or three banks with an external standard hardware interfaces (such as outside the cabinet cleared , barcode recognition, and fingerprint recognition) test, the key is already packaged into a C# controls, just call UsbLibrary.dll file when using the line, do not use that writefile the)

很好的matlab/simulink电子书(ebooks on matlab/simulink)

I have contributed 40 objective type c questions written as source code. Which will be helpful in learning C.
