Наследуясь от класса OutputStream реализовать Иерархию классов FileOutputStream, StringOutputStream, ConsoleOutputStream имеющие соответствующую функциональность.

struct OutputStream
{
    virtual void print( std::string const& s ) = 0;

    virtual void print( int t ) 
    {
        char buff[16] = {};
        sprintf(buff, "%d", t);
        print(buff);
    }

    virtual void print( double t ) 
    {
        char buff[16] = {};
        sprintf(buff, "%f", t);
        print(buff);
    }

    virtual void flush() = 0;

    virtual ~OutputStream() {}
};
