   I have following function:   
   void myfunction (int &a , bool g )   
   {   
   	if(g)   
   	{   
   		int k = a;	   
   	}   
   }   
      
      
   int main()   
   {   
       int * ptr = NULL;   
       myfunction(*ptr, false);   
      
   }   
      
   Is passing null to a reference legal? What standard has to say about   
   this ?
