Using String Header after IOstream header

Question

Honest question here, what,s the point of declaring a #include <string> header when a #include <iostream> header was already declared.

I always thought the string declaration is already available in the iostream standard library, except I have a wrong thought.

Answer 1

C++ in its beginnings didn't know how to work with strings.
Strings used to be represented as arrays of characters.

So, I assume, that's the reason why string declaration is not in iostream declaration - it was added later, and needed a whole new header for itself since C++ is not "made to" work with strings.

Answer 2

C++ doesn't work with strings
