#define LIMIT 1000

void fun2(int n)

{

  if (n <= 0)

     return;

  if (n > LIMIT)

    return;

  printf("%d ", n);

  fun2(2*n);

  printf("%d ", n);

}  

Will it be non terinating recursion if n is negative,if so then why?

If you pass any value less then equals to 0 then it will terminate in the starting condition if( n <= 0 ) return as well as it terminates for value larger then limit (i.e 1000 ).
