              << "Enter a sentence followed by end-of-file:" << std::endl;

    while ((character = std::cin.get()) != EOF) 
       std::cout.put(character);//from   ww  w .j av a  2 s  . c om

    // display end-of-file character
    std::cout << "\nEOF in this system is: " << character << std::endl;
