用huffamn算法实现了文本文件的压缩和解压缩，VC++实现

霍夫曼编码是可变字长编码(VLC)的一种，是消除编码冗余最常用的方法。 它是Huffman于1952年提出一种编码方法，它的基本原理是频繁使用的数据用较短的代码代替，较少使用的数据用较长的代码代替，每个数据的代码个不相同。有时称之为最佳编码，一般就叫作Huffman编码。下面引证一个定理，该定理保证了按字符出现概率分配码长，可使平均码长最短。-Huffman coding is a variable word length coding (VLC) A is to remove redundant code of the most commonly used methods. It is Huffman in 1952 made a coding method, and its basic tenets are frequently used data with the code instead of a shorter, less use of the data over a longer period instead of the code, the code for each data-not the same. Sometimes referred to as the best coding, the general called on Huffman coding. Below prove a theorem, the theorem guarantees by the characters emerging probability distribution yards long, will enable the shortest average yards long.

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，做更多的空间或效率优化。所有代码以C++语言编写，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++库和模板技术。――总之，这些代码的作用在于示例和演示；如果大家想把这些代码应用在实际应用中，可能还需要做进一步的调整和优化。-given here, the source code huffman.zip with eight different ways to achieve the Huffman coding algorithm. The code is intended to demonstrate different Huffman Algorithm of principle, the implementation of efficient algorithms compare the difference, but not against the actual application environment needs to do more space or efficiency optimization. All of the code is written in C, in order to more easily achieve various data structure, large-scale application of the code of the standard C library and template technology.-- In general, these is the role of code examples and demonstrations; If you want to use the code in practical application, we may need to do further restructuring and optimization.
