HuffMan
哈夫曼编码译码系统,设置发送者和接受者两个功能,
发送者的功能包括:
①输入待传送的字符信息;
②统计字符信息中出现的字符种类数和各字符出现的次数(频率);
②根据字符的种类数和各自出现的次数建立哈夫曼树;
③利用以上哈夫曼树求出各字符的哈夫曼编码;
④将字符信息转换成对应的编码信息进行传送。
接受者的功能包括:
①接收发送者传送来的编码信息;
②利用上述哈夫曼树对编码信息进行翻译,即将编码信息还原成发送前的字符信息。
(Huffman decoding system, set the sender and the recipient of two functions, the sender' s features include: (1) input to be transmitted character information ② statistical character information, the number of types of characters and characters the number of occurrences (frequency create a Huffman tree) ② According to the number of types of characters and their respective number of occurrences ③ use the Huffman tree to find the characters Huffman coding ④ character information into the corresponding coding information for delivery. The recipient of the features include: (1) to receive the coded information to the sender transmission ② above Huffman tree coded information to be translated, is about to coded information to restore the character information before sending.)

HuffmanCode
Huffman 编码是第一个实用的无损压缩编码技术,经过了多年的不断改进,已经形成了系统的理论和方法。目前主要有两种类型的Huffman编码方式,即静态Huffman编码和动态Huffman编码。Huffman编码有着广泛的应用,但是不再是压缩算法的全部,而是被当作最终的编码方法。(Huffman coding is the first practical lossless compression coding technology, after years of continuous improvement, has formed a system of theories and methods. There are currently two types of Huffman encoding, namely, static and dynamic Huffman coding Huffman coding. Huffman coding has been widely used, but the compression algorithm is no longer all, but rather be treated as the final coding.)

赫夫曼编译码器:
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,这要求在发送端通过一个编码系统对待传数据预先编码,在接收端将传来的数据进行译码(复原)。对于双工信道(即可以双向传输信息的信道),每端都需要一个完整的编/译码系统。试为这样的信息收发站写一个哈夫曼码的编/译码系统。
[基本要求]一个完整的系统应具有以下功能:
(1)I:初始化(Initialization)。从终端读入字符集大小n,以及n个字符和n个权值,建立哈夫曼树,并将它存于文件hfmTree中。
(2)E:编码(Encoding)。利用已建好的哈夫曼树(如不在内存,则从文件hfmTree中读入),对文件ToBeTran中的正文进行编码,然后将结果存入文件CodeFile中。
(3)D:译码(Decoding)。利用已建好的哈夫曼树将文件CodeFile中的代码进行译码,结果存入文件TextFile中。
(4)P:印代码文件(Print)。将文件CodeFile以紧凑格式显示在终端上,每行50个代码。同时将此字符形式的编码文件写入文件CodePrin中。
(5)T:印哈夫曼树(Tree printing)。将已在内存中的哈夫曼树以直观的方式(树或凹入表形式)显示出,同时将此字符形式的哈夫曼树写入文件TreePrint中。()
