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 (The given here source code huffman.zip eight different ways to achieve the Huffman coding algorithm. 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. The entire code C++ language development code in order to make it easier to achieve a variety of data structures, a large number of applications the standard C++ library template.- In short, these code examples and demonstration If we want the code used in practical applications may also need)
