这是COBOL的练习题目，可以有点参考价值

For any software that handles client requests, at some point, there must be a persistent point where all data related to the clients are stored. Those storages can be any thing (database, mainframes, files etc.). What if this software needs to access those storages with concurrent requests, knowing that opening a connection is memory and CPU consuming? A Connection Pool is a container of open and reusable connections. It will help you save both memory and CPU time. Also, it will help you in managing connections.

C 程序设计语言定义了两个标准的内存管理函数：malloc() 和 free()。C 程序员经常使用那些函数在运行时分配缓冲区，以便在函数之间传递数据。然而在许多场合下，您无法预先确定缓冲区所需的实际大小，这对于构造复杂的 C 程序来说，可能会导致几个根本性的问题。一种自我管理的抽象数据缓冲区概括地给出了抽象缓冲区的伪 C 代码实现，并详细介绍了采用这种机制的优点。-C programming language defines two standard memory management functions: malloc () and free (). C programmers frequently use those functions at run-time allocation of buffers in order to pass data between functions. However, in many occasions, you can not pre-determine the actual size of the buffer required, which for the complex structure of the C program, it may lead to several fundamental questions. A self-management, abstract data buffer generally gives the pseudo-C code for an abstract buffer implementation, and details the advantages of using this mechanism.

Hamming 神经网络从功能上来看是最小Hamming 距离分类器．利用它能够完成不完整输入信息与所存储模式的最小汉明距离分类． 　　 Hamming 网络是一个双层神经网络，第一层网（即匹配子网络）是用来计算输入模式与该网络已经学习过的各样本之间的匹配测度．第二层网（即竞争子网络）接收从匹配子网络送来的未知模式与已存各样本的匹配测度，然后经过多次迭代运算就可以求得与输入模式相匹配的样本．-Hamming neural network from the functional point of view is the smallest Hamming distance classifier. Use it to complete incomplete input information storage model with the smallest Hamming distance classifier. Hamming network is a double neural network, the first network layer (ie matching sub-network) is used to calculate the input model and the network has been studied by the match between the sample test degrees. The second layer network (that is, competitive-network) from the receiver-matching network sent an unknown model has been deposited with the samples matching measure, Then after many iterative computation can be obtained with the input mode matching sample.
