Thread: Help to copy files in c++

I might be wrong, but I think that is bound to copy each byte properly... Any thoughts?

It may well do the right thing, but it's certainly not going to be very efficient, as discussed above. And it's likely that it won't work right for control characters like CR ('\r') and CTRL-D/Z (EOF indicator on text files). It may well work OK if you open the file in binary mode, but I doubt << operator is guaranteed for binary input.

We covered this sometime ago in the thread reading text.

Why do you want to do that? What problem are you trying to solve by doing it?
I've never tried to write a self-extracting .exe file, but I'm sure it's not an easy task.

Just that it will copy files from itself to a location. Do you know such program?

You can create such a self-extracting archive using 7-zip.
