Sure, but the inventors of the language (C) believed in maximum modularity and tried to make the language itself (the built-in "keywords" and symbols) as small as possible. This design has served the world well as C and its derivitives have been to put to great use in environments unlike the one it was first created for (a PDP-7).
The software embedded in your webcam, for example, likely was written in C or C++. It doesn't have "a console" or anywhere to "print", so any logic to support that function would have been a waste of resources on such a device. It's great that such functions are not requirements of the language itself.
