示例1: main

if(! infile.good() )
cerr<<"Can't open input file!"<<endl;
BitInputStream in(infile);
/** First read in the file and count the freq of every byte
*/
unsigned char temp;
while(1)
{
temp=in.readByte();
if(in.eof())
break;
freqs[temp]++;
}
infile.close();
#define testinput
#ifndef testinput
#define testinput
for (int i=0;i<256;i++)
{
cout<<setw(6)<<i<<": "<<setw(6)<<freqs[i];
if (i%4==3)
cout<<endl;
}
#endif
//build tree;
tree.build(freqs);
outfile.open(argv[2],ios_base::binary);

//write header to target file
