網絡上找到的好多方法在解壓縮字符串的時候會丟失字符，這里是解決方法:

http://stackoverflow.com/questions/21186535/compressing-decompressing-char-array-using-zlib-some-characters-missing

基于此，筆者修改了一下，由于是初學者，只按照編譯器不報錯的原則修改了一下，能運行

打開vc++6.0新建控制臺程序程序,配置好zdll.lib,把zlib1.dll放置到合適的位置

主程序main.cpp如下

#include <string.h> #include <stdio.h> #include <stdlib.h> #include "zlib.h"int main() {const char *istream = "some foo漢字";uLong srcLen = strlen(istream)+1; // +1 for the trailing `\0`uLong destLen = compressBound(srcLen); // this is how you should estimate size // needed for the bufferunsigned char* ostream = (unsigned char*)malloc(destLen);int res = compress(ostream, &destLen, (const unsigned char *)istream, srcLen); // destLen is now the size of actuall buffer needed for compression// you don't want to uncompress whole buffer later, just the used partif(res == Z_BUF_ERROR){printf("Buffer was too small!\n");return 1;}if(res == Z_MEM_ERROR){printf("Not enough memory for compression!\n");return 2;}unsigned char *i2stream = ostream;char* o2stream = (char *)malloc(srcLen);uLong destLen2 = destLen; //destLen is the actual size of the compressed bufferint des = uncompress((unsigned char *)o2stream, &srcLen, i2stream, destLen2);printf("%s\n", o2stream);return 0; }
