copy a file

[Severin Ecker]

hi!

i'm trying to copy a file with the std::copy function but my problem is,
that whitespaces are discarded. could anyone tell me how i can just copy all
the characters that are in the source-file. thx.

std::istream_iterator<std::string> ins(in), eos;
std:stream_iterator<std::string> outs(out);
std::copy(ins, eos, outs);

thanks,
sev

std::istream_iterator<std::string> ins(in), eos;

std::copy(ins, eos, outs);

You can have the ostream_iterator output a separator if you give it a second
arg:
std:stream_iterator<std::string> outs(out,'\n');

Do you really want to be doing formatted I/O?
If you want to literally copy the file, it's probably better to use use a loop of
read/write combintations (or getline at the worst).

std::ifstream In(SrcFilename, std::ios::binary);
std:fsteam Out(DstFilename, std::ios::binary);

Out << In.rdbuf();

Voilà
This will make an exact copy of the input file.
