(C++) How do I copy a file?

include <fstream>

include <cassert>


void copyFile(const std::string& fileNameFrom, const std::string& fileNameTo)
{
  assert(fileExists(fileNameFrom));
  std::ifstream in (fileNameFrom.c_str());
  std::ofstream out(fileNameTo.c_str());
  out << in.rdbuf(); 
  out.close();
  in.close();
}
