Answer 2

Funny you should ask. I found myself in a similar position and did some research. So here's why:

endl appends '\n' to the stream and calls flush() on the stream. So

cout << x << endl;

is equivalent to

cout << x << '\n';
cout.flush();

Here's an interesting discussion on why flushing may be necessary.
