Hi All,
    I am trying to allocate memory for member variable in a static
method belongs to same class.. the allocation is o.k and when try to
access the member variable I find that it is a null pointer.

Here is the code ...

#include <iostream.h>

class A
{
public:
 A():i(0){}
 ~A(){ if(i) { delete i; i = 0;}}
 static void create(A** obj)
 {
  *obj = new A();
  int* ii = 0;
  (*obj)->get_i(ii);
  ii = new int;
 }
 void get_i(int*& g_out)
 {
  g_out = i;
 }
private:
 int* i;
};

int main()
{
 A* ob = 0;
 A::create(&ob);
 int* i = 0;
 ob->get_i(i);
 try
 {
  cout << " value " << *i << endl;
 }catch(...)
 {
  // thows the null pointer exception
 }
 if( ob ) { delete ob; ob = 0;}
 return 0;
}

Any suggestions in this regard is welcome.

Thanks
Chandra-
