BitIOTest1
这是一个练习使用位写入/写出的程序,利用bitio.c和bitio.h工具整合,可以向文本文件E:\bitio1.txt中读取和写入数个位,使用者可以通过调试功能进一步了解位写入写出的作用。进而给今后做数据压缩打下基础。(This is a practice using bit write/write program, using bitio.c and bitio.h tool integration, you can read and write several bits to the text file E: \ bitio1.txt, the user can pass Debugging function to further understand the role of bit write write. And then lay the foundation for future data compression.)

呃,就是用赫夫曼算法写的压缩解压程序。非常粗糙,只能压缩英文文章。因为里面的字符概率是基于自然语言的,源代码之类的没法压缩。而且会抛弃最后几个字母,嘿嘿。为了交作业,没有好好写。改一下下应该能挺好的。压缩比能到60 吧(Uh, is to use Huffman compression decompression algorithm written procedures. Very rough, only compress English articles. Because there is the probability of characters based on natural language, the source code and the like can not compressed. And will abandon the last few letters, hehe. For homework, not properly written. The following should be able to change it quite good. Compression ratio to 60 of it can be)

DS4
设电文字符集D及各字符出现的概率F如下:
D={a,b,c,d,e,f,g,h}(字符数n=8)
F={5,29,7,8,14,23,3,11}( )
编写完成下列功能的程序:
①构造关于F的Huffman树;
②求出并打印D总各字符的Huffman编码。
程序结构: 类型说明;
构造Huffman树的函数:Huffman_tree(H[m+1]);
求Huffman编码的函数:Huffman_code(code[n+1]);
main()
{ 变量说明;
输入字符集D及频率F;
调用Huffman_tree(H);
调用Huffman_code(code);
打印编码;
Y 继续?
