This is simple concept that the null pointer has the value of 0 while the unitialized pointer has the garbage value which pointing anywhere in the memory.

No, because pointers initially contains garbage values.

Uninitialized pointer results in the dangling pointer. So, both are different.

In my view, a uninitialised pointer is that which is not pointing to anywhere, and a null pointer is also same. Because while coding we get to a sometime situation when we don't want to initialise a pointer at beginning AND SO FOR THAT WE INITIALIZE IT WITH THE NULLVALUE. SO IN THE CASE OF UNINITIALISED ALSO.
