这里给出的源代码huffman.zip用8种不同的方式实现了Huffman编码算法。这些代码意在演示不同Huffman算法的实现原理,比较算法执行效率的差别,但并没有针对实际应用环境的需求,做更多的空空空间或效率优化。全部代码以C++语言开发,为了更容易地实现各种数据结构,代码中大量应用了标准C++库与模板技术。——总之,这些代码的作用在于示例与演示;如果大家想把这些代码应用在实际应用中,可能还需要

These codes are intended to demonstrate different Huffman algorithm implementation principle, the difference of the algorithm execution efficiency, but does not demand for practical application environment, do more empty space or efficiency optimization.

哈夫曼编码(Huffman Coding),又称霍夫曼编码,是一种编码方式,哈夫曼编码是可变字长编码(VLC)的一种。Huffman于1952年提出一种编码方法,该方法完全依据字符出现概率来构造异字头的平均长度最短的码字,有时称之为最佳编码,一般就叫做Huffman编码(有时也称为霍夫曼编码)。(Huffman encoding (Huffman Coding), also called Huffman Coding, is a way of Coding, Huffman Coding is variable word length Coding (VLC). Huffman in 1952 put forward a kind of coding method, this method is completely based on the characters of the occurrence probability to construct the average length of the shortest code word, sometimes called the best coding, generally is called Huffman coding (sometimes referred to as the Huffman coding).)
