Why can a function not have a Static parameter? [closed]

Question

The following is the code in c.

     fact(2);
     void fact(static int i)
     {..}

Output:Error cannot have static arguments
So why can't we have static arguments in a function?

Answer 1

The static keyword means that a variable may have only and exactly one instance in its scope, and that instance is invisible out of its scope. Neither of these requirements make sense for a function argument: it may be called multiple times, at a different memory address, and as it's meant for communication, it has to be visible to the outer world.

Answer 2

Trying to apply static to an argument doesn't make much sense, so the standard doesn't allow it (§6.7.5.3/2: "The only storage-class specifier that shall occur in a parameter declaration is register.")
