The null pointer will not be pointing to any location but uninitialized pointer can have garbage value which would point to some location.

Uninitilized pointer can have any garbage value and this garbase value point to some memory location. But if you initilize the point with null value (i.e. 0) then it will point to no where. Pointer initilized with NULL value is very usefull in preventing the accidental error, deffects etc. Pointer NULL initilization is highly practiced in industry.
