 ==== Extern ====
-You should '''ignore''' it since its the default when there's no anything set. It means that you can use and/or re-declare a function on other ''files'' of the code
+Since it is the default value out of any function (global mode), you should ignore it. You can use it too for say that a variable is declared from a different (outside) file
 
 ==== Static ====
 You can use ''static'' inside a function or outside it, it has two different meanings:
-     * Inside a function: You can ''pre'' set a value to a variable ''(static int foo = 5)'', then the first time you enter on the function it will be set to 5, but the next times it not set again, it just remember the last value used
-     * Outside a function (global mode): You will use it only in the actual file (compilation unit), good for optimization but you can't use it on other files
+ * Inside a function: You can ''pre'' set a value to a variable ''(static int foo = 5)'', then the first time you enter on the function it will be set to 5, but the next times it not set again, it just remember the last value used

+Also, you can use the static variable (out of any function) in order to avoid a double-declaration of the same variable, when you use static (globally) it is limited to the file so, in another file is a different variable without any relation.
