（1） I:初始化,从终端读入n个字符和n个权值,建立哈夫曼树,并将它存放在文件HuffmanTree中.

（2）E:编码.利用已建立好的哈夫曼树,对要传输的数据正文(存在文件ToBeTran.txt中)进行编码,将结果代码存(传输)到文件CodeFile中.

（3）D:译码.利用已建好的哈夫曼树,对传输到达的CodeFile中的数据代码进行译码,将译码结果存入文件TestFile中.

（4） P: 印文件.将文件CodeFile以紧凑格式显示在终端上，每行50个代码。同时将此字符形式的编码文件写入文件CodePrin中。

（5） T:,印哈夫曼树,将内存中的哈夫曼树以直观的方式(可以树或凹入表的形式)显示在终端上，同时将此字符形式的编码文件写入文件TreePrin中。

-(1) I: initialization, read from the terminal n-n-weight character and to build the Huffman tree, and store it in the file HuffmanTree.

(2) E: coding. Using Huffman tree has been well-established, the body of data to be transferred (in the existing file ToBeTran.txt) encoding, the result code deposit (transfer) to a file in the CodeFile.

(3) D: decoding. Use of the Huffman tree has been completed, the transmission of data to reach the CodeFile code decoding, the decoding results stored in the file TestFile.

(4) P: printing documents. CodeFile file to the terminal on the compact format, each line of code 50. While this character is written in the form of the encoded file in the file CodePrin.

(5) T:, India Huffman tree, the Huffman tree in memory in an intuitive way (for the tree or recess in the form of tables) displayed in the terminal, but this character in the form of encoded file written to the file TreePrin in.
