[I changed the name of variable inside the function to b, as I need some
clarification here.]
static const char a[] = "testme";
void foo () { puts (a); }
int main()
{
extern const char b[];
puts (b);
foo ();
}
In this example,
-- a is file scope.
-- b is function scope (but external linkage). Correct ?
CTF does not need to identify C type of variable b. But does need to identify C
type of variable a.
