When Are Pointers Equal?

When Are Pointers Equal?

Pointers to objects or functions of the same type are equal if and only if in they are both NULL:

   int *p1 = NULL, p2 = NULL;  bool equal = (p1==p2); //true

Or if they point to the same object:

   char c;  char * pc1 = &c;  char * pc2 = &c;  equal = (pc1 == pc2); // true

Additionally, pointers are equal if they point one position past the end of the same array.
