说明： I ve written some many years ago dynamic Huffman algorithm to compress and decompress data. It is mainly targeted to data with some symbols occuring more often than the rest (e.g. having some data file consisted of 3 different symbols and their total number of occurence in that file s1(1000), s2(200), s3(30) so the total length of file is 1000+200+30=1230 bytes, it will be encoded assigning one bit to s1 and 2 bits to s2, s3 so the encoded length will be 1*1000+2*(200+30)=1460 bits=182 bytes). In the best case the file consisted of just one symbol will be encoded with compression ratio as 1:8. Huffman coding is used in image compression, however in JPEG2000 arithmetic codec is imployed.

CONSOLE APPLICATION : huffman Project Overview
========================================================================
AppWizard has created this huffman application for you.
This file contains a summary of what you will find in each of the files that
make up your huffman application.
huffman.vcproj
This is the main project file for VC++ projects generated using an Application Wizard.
It contains information about the version of Visual C++ that generated the file, and
information about the platforms, configurations, and project features selected with the
Application Wizard.
huffman.cpp
This is the main application source file.
/////////////////////////////////////////////////////////////////////////////
Other standard files:
StdAfx.h, StdAfx.cpp
These files are used to build a precompiled header (PCH) file
named huffman.pch and a precompiled types file named StdAfx.obj.
/////////////////////////////////////////////////////////////////////////////
Other notes:
AppWizard uses "TODO:" comments to indicate parts of the source code you
should add to or customize.
