• A global variable has external linkage by default. Its scope can be extended to files other than containing it by giving a matching extern declaration in the other file.
  The scope of a global variable can be restricted to the file containing its declaration by prefixing the declaration with the keyword static. Such variables are said to have internal linkage.
