Question

wyh insted of

cout << "Hello world! \n\n";
cout << "I love programming!";

we dont write it in only one line ???

Answer 1

In fact, You can. It's the matter of preference to put it this way

cout << "Hello world! \n\nI love programming!";

or this

cout << "Hello world! \n\n"
<< "I love programming!";

or this

cout << "Hello world! \n\n";
cout << "I love programming!";

But as you see, the third one uses an additional `cout` object which can be dropped, for the most part.
