. We hope that it will be useful and interesting for you, as well as our listeners. 3r33737.  3r33770. 3r33737.  3r33770. Go. 3r33737.  3r33770. 3r33737.  3r33770. Have you ever come across the terms internal and external communication? Want to know what the extern keyword is used for, or how does declaring something static affect the global scope? Then this article is for you. 3r33737.  3r33770. 3r33737.  3r33770. 3r3744. In a nutshell,
 3r33770. 3r33737. 3r33737.  3r33770. The translation unit includes the implementation file (.c /.cpp) and all its header files (.h /.hpp). If an object or function has an internal binding within a translation unit, then this symbol is visible to the linker only within that translation unit. If the object or function has an external binding, then the linker will be able to see it when processing other translation units. Using the static keyword in the global namespace gives the symbol internal binding. The keyword extern gives external linking. 3r33737.  3r33770. The default compiler gives the characters the following bindings:

Non-const global variables - external binding; 3r3699.  3r33770.
Const global variables - internal binding; 3r3699.  3r33770.
Functions - external binding. 3r3699.  3r33770.
