Answer 2

^{It is not Eclispe (which is an editor, not a compiler; probably your Eclipse would run a compiler like GCC using the g++ program; and then you are running the compiled executable.).}

If you don't see your expected output, it is probably because your output stays buffered.

You could try the std::flush manipulator.

   for (int i=0; i <5; i++)
        std::cout << i << std::flush;

See this question and the several good answers there.

You might read more about the std::endl manipulator. I suggest doing std::cout << std::endl from time to time.

You could consider using the std::clog output stream.
