i am trying to write a program that can copy a binary file (exe). nothing i have tried has worked, i initially tried to copy the entire file into a character array but i assume binary files use characters that make the compiler prematurely terminate the string. the closest i have come so far is

fstream outfile("write.exe", ios::out|ios::binary|ios::trunc);
for (counter=0;counter> x;
outfile x;
}

where endf is the length of the file to be copied. this almost works but the resultng program makes an illegal error immediately on startup. i have been searching the net for hours and can't figure this one out :(

i didnt realize code doesnt post on here. what i meant to post was

fstream outfile("write.exe", ios::out|ios::binary|ios::trunc);

     for (counter=0;counter> x;

         outfile  x;

     }

I'm not sure if you've already tried this, but I think it would make things a whole lot simpler if you just used a system call like cp for nix, or it's DOS equivelant copy. I *think* you can do that with just SYSTEM("copy [source file] [dest file]"); in DOS, but I'm not sure. Try looking up how to call DOS command-line calls if that doesn't work.
