huffman编码.

把一个英文字母,空格,句号.一共有28个 character.

先求每个字符出现的频率.

然后用频率对这个文件进行哈夫曼编码.

然后再进行解码.



运行的时候需要在VC++ 工程->设置->调试->程序变量里加E:\\sample.txt E:\\encode.txt E:\\decode.txt

然后把英文文件放到E盘里.名叫samole.txt,

还有在E里新件2个txt文件.名叫encode.txt,decode.txt.

编码后的二进制save到encode.txt,解码后的英文字符save到decode.txt了.-Huffman coding. One English letters, spaces, full stop. A total of 28 character. Every character in first seeking the frequency. Then the frequency of text pieces for Huffman coding. then decode. When running in VC -
