Use this function for binary file copying. Call it to copy files of any type?executables, images, not just text files. The argument infilename represents the (full) path to the original file and outfilename is the name of the copy.

#include void filecopy(char *infilename, char *outfilename){   char c;   // The buffer.   // Open input file.   fstream in(infilename, ios::in | ios::binary);   // Create output file.   fstream out(outfilename, ios::out | ios::binary);   // Copy file.   while(1)   {      c = in.get();      if(in.fail()) break;      out.put(c);   }   // Close files.   in.close();   out.close();
