Question

int WriteFile(char*pFilename,HEAD sHead,char*pBuffer,int nSize)
{
    char filename[256]={0};
    strcpy(filename,pFilename);
    int i;
    for(i=strlen(filename);filename[i]!='.';i--);
      filename[i]='\0';
    strcat(filename,".huf");
    FILE*out=fopen(filename,"wb+");
    fwrite(&sHead,sizeof(HEAD),1,out);
    fwrite(pBuffer,sizeof(char),nSize,out);
    fclose(out);
    out=NULL;
    cout<<"生成压缩文件:"<<filename<<endl;
    int len=sizeof(HEAD)+strlen(pFilename)+1+nSize;
    return len;
}

Answer 1

改成

int WriteFile(char*pFilename,const HEAD sHead,char*pBuffer,int nSize)
{
    char filename[256]={0};
    strcpy(filename,pFilename);
    int i;
    for(i=strlen(filename);filename[i]!='.';i--);
      filename[i]='\0';
    strcat(filename,".huf");
    FILE*out=fopen(filename,"wb+");
    fwrite(&sHead,sizeof(HEAD),1,out);
    fwrite(pBuffer,sizeof(char),nSize,out);
    fclose(out);
    out=NULL;
    cout<<"生成压缩文件:"<<filename<<endl;
    int len=sizeof(HEAD)+strlen(pFilename)+1+nSize;
    return len;
}
