Reading and writing binary file

If you want to do this the C++ way, do it like this:

#include <fstream>
#include <iterator>
#include <algorithm>

int main()
{
    std::ifstream input( "C:\\Final.gif", std::ios::binary );
    std::ofstream output( "C:\\myfile.gif", std::ios::binary );

    std::copy( 
        std::istreambuf_iterator<char>(input), 
        std::istreambuf_iterator<char>( ),
        std::ostreambuf_iterator<char>(output));
}

If you need that data in a buffer to modify it or something, do this:

#include <fstream>
#include <iterator>
#include <vector>

int main()
{
    std::ifstream input( "C:\\Final.gif", std::ios::binary );

    // copies all data into buffer
    std::vector<unsigned char> buffer(std::istreambuf_iterator<char>(input), {});

}

Here is a short example, the C++ way using rdbuf. I got this from the web. I can't find my original source on this:

#include <fstream>
#include <iostream>

int main () 
{
  std::ifstream f1 ("C:\\me.txt",std::fstream::binary);

  std::ofstream f2 ("C:\\me2.doc",std::fstream::trunc|std::fstream::binary);

  f2<<f1.rdbuf();

  return 0;
}
