说明：   哈夫曼编码/译码 背景介绍： 　　利用哈夫曼编码进行通信可以大大提高信道利用率，缩短信息传输时间，降低传输成本。但是，这要求这发送端通过一个编码系统对待传数据预先编码，在发送端将传来的数据进行译码（复原）。对于双工信道。每端都需要一个完整的编译码系统。本程序将为这样的信息收发站写一个哈夫曼的编译码系统。 哈夫曼编码/译码： 程序运行步骤： １、建立哈夫曼树，从键盘输入字符集大小，字符以及频度。 ２、对字符进行编码，输出编码结果，分单个句子和整个句子输出，编码导入和导出CodeFile。 ３、对哈夫曼码进行翻译。 运行环境：　　windows XP 语言环境：　　简体中文 软件大小：　　144 KB 编写工具： Microsoft Visual C++ 6.0 操作环境: MFC
(Huffman encoding/decoding background information : Huffman coding used in communication can greatly improve the channel utilization, reduced transmission time, and lower transmission costs. However, this requires that the sender through a coding system for pre-treatment data-coding, the transmitter will be sent for decoding data (recovery). For dual-channel. Each side needs a complete encryption system. This procedure will this information hubs Huffman was one of the encryption system.
