does the <iostream> load <string> as well?

Question

including libraries

Answer 1

No, and it's, in my opinion, also not sad. Separation of concern is *the* means for clean reusability.

Answer 2

Sadly not.

Answer 3

Unfortunately it does not. You will need to include both <iostream> and <string> in your header.

Answer 4

The <string> library is included in <iostream> library.
So you do not need to write it if you are using <iostream> .
