Pointer Blues's a cool scene! Dig it!

  Pointers aren't hard to grasp. Why do people have so many problems
with them?

  Wrong! A pointer is a pointer is a pointer is a pointer is not an
array. An array is an array is an array is an array is not a pointer.
A pointer points. An array does not point. An array holds consecutive
elements of a particular type. A pointer does not hold consecutive
elements of a particular type. A pointer holds an address. An array
does not hold an address (unless it is an array of pointer, of
course).
  A 2D array is really an array of array.
