用C或C++怎样生成自解压程序,该怎么处理

用C或C++怎样生成自解压程序
用C或C++怎样生成自解压程序，即在VC中是否有生成压缩与解压缩和相关API

[解决办法]
VC中好象没有
不过有相关的库可以用
比如.ziplib等等
[解决办法]
//用zlib实现压缩与解压缩
//在winxpsp2+devc++4.9.9.2实现
//链接参数中加入-lz
//将zlib1.dll加入程序目录
//kzip功能是压缩文件,kunzip是解压缩文件
//仅限于对单个文件的压缩与解压缩
＃i nclude <cstdlib>
＃i nclude <iostream>
＃i nclude <zlib.h>
＃i nclude <stdlib.h>

using namespace std;
void kzip(char *inFile,char *outFile)
{
FILE *FileIn=fopen(inFile, "rb ");
FILE *FileOut=fopen(outFile, "wb ");
fseek(FileIn,0,SEEK_END);
unsigned long FileInSize=ftell(FileIn);
void *RawDataBuff=malloc(FileInSize);
void *CompDataBuff=NULL;
uLongf CompBuffSize=(uLongf)(FileInSize+(FileInSize*0.1)+12);
CompDataBuff=malloc((size_t)(CompBuffSize));
fseek(FileIn,0,SEEK_SET);
fread(RawDataBuff,FileInSize,1,FileIn);
uLongf DestBuffSize;
compress2((Bytef*)CompDataBuff,(uLongf*)&DestBuffSize,(const Bytef*)RawDataBuff,(uLongf)FileInSize,Z_BEST_COMPRESSION);
fwrite(CompDataBuff,DestBuffSize,1,FileOut);
}
void kunzip(char *inFile,char *outFile)
{
//the input file, this is the output file from part one
FILE *FileIn = fopen(inFile, "rb ");

//output file
FILE *FileOut = fopen(outFile, "wb ");

//get the file size of the input file
fseek(FileIn, 0, SEEK_END);
unsigned long FileInSize = ftell(FileIn);

//buffers for the raw and uncompressed data
void *RawDataBuff = malloc(FileInSize);
void *UnCompDataBuff = NULL;

//read in the contents of the file into the source buffer
fseek(FileIn, 0, SEEK_SET);
fread(RawDataBuff, FileInSize, 1, FileIn);
//allocate a buffer big enough to hold the uncompressed data, we can cheat here
//because we know the file size of the original
uLongf UnCompSize = 482000;
UnCompDataBuff = malloc(UnCompSize);


//all data we require is ready so compress it into the source buffer, the exact
//size will be stored in UnCompSize
uncompress((Bytef*)UnCompDataBuff, &UnCompSize, (const Bytef*)RawDataBuff, FileInSize);

//write the decompressed data to disk
fwrite(UnCompDataBuff, UnCompSize, 1, FileOut);
