what's the danger with calling the function more than once?

int* create() {
    static int p = 0;
    p++;
    return &p;

BTW, you mean
::printf("%d %d", *(create()), *(create()));

<br />
int* create( )<br />
{<br />
    static int p = 0;<br />
    p++;    <br />
    return &p;<br />
}<br />

int create2( )<br />

	return p;<br />

Correct me if I'm wrong, but as far as I remember, a static variable gets a fixed position on the heap.

void  effect( void )
{
    int change = 1;
}
 
int main( )
{
  int *p;
  p = create();
 
  effect();
 
  cout ...
 
  ...
}
