压缩与解压缩类；压缩文件至.zip包内，增加文件至.zip包内，及解压缩相关操作。(zip and unzip。)

upx解压，演示upx解压的程序源码，仅供参考。(upx unpack，show upx unpack program source code)

赫夫曼编/译码器源码，已生成的每个字符的赫夫曼编码，对任意字符文本进行编码，再译码(Huffman encoder/decoder source code, Huffman coding, each character has been generated, the text of any character encoding, decoding)

RLE是一个压缩的算法，里面有算法的C++程序实现。(RLE is a compression algorithm, there are algorithms C++ program)

16字节字符串压缩成12字节字符串算法，有压缩和解压的算法(16-byte string into a 12-byte string compression algorithm, compression and decompression algorithms)

利用gzip.dll解压http请求返回的内容。内附gzip.dll。参考网上资料自己写的VB6工程源码。自己编译EXE的时候注意把gzip.dll释放到exe所在目录。(Use gzip.dll to decompress the content returned by HTTP request. Gzip.dll is attached. Refer to the VB6 project source code written by myself.)

霍夫曼编码的C++实现,输入一组字符串，输出每个字符的编码及整个字符串的霍夫曼编码。(realization of Huffman coding using VC++)

zip压缩源代码，附有整个工程，保证能用，可应用于文件压缩，内存压缩(zip compressed source code, with the whole project, and ensure that use, can be applied to file compression, memory compression)

视音频课程作业，对视频抽帧，对单张图片进行yuv420采样、DCT变化、量化以及反量化、IDCT变化(Jpeg Encoding & Decoding)

这里给出的源代码huffman.zip用8种不同的方式实现了Huffman编码算法。这些代码意在演示不同Huffman算法的实现原理，比较算法执行效率的差别，但并没有针对实际应用环境的需求，做更多的空空空间或效率优化。全部代码以C++语言开发，为了更容易地实现各种数据结构，代码中大量应用了标准C++库与模板技术。——总之，这些代码的作用在于示例与演示；如果大家想把这些代码应用在实际应用中，可能还需要 (The given here source code huffman.zip eight different ways to achieve the Huffman coding algorithm. These codes are intended to demonstrate different Huffman algorithm implementation principle, the difference of the algorithm execution efficiency, but does not demand for practical application environment, do more empty space or efficiency optimization. The entire code C++ language development code in order to make it easier to achieve a variety of data structures, a large number of applications the standard C++ library template.- In short, these code examples and demonstration If we want the code used in practical applications may also need)
