#include <iostream>
using std::cout;
using std::endl;
using std::ios;

#include <fstream>
using std::ifstream;
using std::ofstream;

int mainint argc, char *argv[] )
{
   // check number of command-line arguments
   if argc != )
      cout << "Usage: copyFile infile_name outfile_name" << endl;
   else
   {
      ifstream inFileargv], ios::in );
      if !inFile )
      {
         cout << argv<< " could not be opened" << endl;
         return -1;
      }

      ofstream outFileargv], ios::out );
      if !outFile )
      {
         cout << argv<< " could not be opened" << endl;
         inFile.close();
         return -2;
      }

      char c = inFile.get();

      while inFile )
