What is the use of making a global

[Guest_imported]

What is the use of making a global variable "static" i.e.

static int x;

main ()
{
..
}

Hi,

If I remember correctly you make a global var static if you have a var with the same name in another file in the same project.
Below is taken from M$.'s mscxx.hlp.

When modifying a variable or function at file scope,
the static keyword specifies that the variable or function has internal linkage (its name is not visible from outside the file in which it is declared).

Hope that helps.

When making a global variable static in a file you make sure that this variable is only visible from within the same file, and therefore it can't be accessed from any external file.
