iostream has diamont of ios, istream, ostream because of virtually inherits from ios for more than subtyping purposes

Implementation Structure
Input/Output
The iostream library is an object-oriented library that provides input and output functionality using streams. A stream is an abstraction that represents a device on which input and ouput operations are performed. A stream can basically be represented as a source or destination of characters of indefinite length.

Lecture 3
Unlike Java, C++ allows a class to inherit from more than one class, thus the inheritance hierarchy may form an arbitrary DAG. Using multiple inheritance, a class cannot only represent a subtype of more than one possibly unrelated supertype, but it can inherits fields and methods, and thus implementation aspects, of more than one class.

C++ :: std:: 접두어와 iostream 헤더파일 #2
'#'은 전처리기이다. 전처리기는 컴파일을 시작하면, 우선적으로 처리한다. iostream 은 cout, cin, endl 등 기본 입출력과 관련된 객체들을 정의한 헤더파일이다. iostream은 표준 라이브러리 디렉토리에 존재한다. (표준 라이브러리는 컴파일러 제작사가 만들어서 헤더파일을 이용해 배포 함.) 표준라이브러리에 있는 변수나 함수는 std 표준 네임스페이스에 포함되어있다. 그래서 표준 라이브러리를 사용할 때는 std::접두어를 붙여야한다.
