iostream is indeed a class in C++. You obtain access to this class by including the file named iostream in your code:

// SomeFile.cpp
#include <iostream>

// Some code that makes use of the class iostream...

This also holds for other stream classes within C++ such as istream, ostream, fstream, and so forth. Dig around in the include directory of your C++ installation to get a look at these classes if you wish.

This is of course a very common situation in C++ since one often encounters classes whose actual definitions are stored in files with the same name as the class but with .hpp or .cpp extensions.

... Or both. You can include the header <iostream> and there is a type std::iostream
