根据ascii码文件中各ascii字符出现的频率情况创建Haffman树，再将各字符对应的哈夫曼编码写入文件中，实现文件压缩。-In accordance with ascii code ascii characters in the document the frequency of the situation created Haffman tree, and then the character of the Huffman code corresponding to write docu

利用哈夫曼树对asc码文件进行编码 压缩解压 VC6.0编的-Use Huffman code tree for the asc file encoding decompression VC6.0 compiled

基于ASC码的哈弗曼编码压缩，只能用于txt文件的压缩-Huffman encoding and compression for compressing txt files only
