Therefore, so it goes on, in the deconstruction stage when we empty what Envelope #1 is carrying, by setting it to NULL. To wrap everything up, I thought if you think of a pointer as a dollar bill, that you pass succinctly from memory slot to memory slot, that is by far the most clearest explanation of a pointer of all.
To literally ‘pass the buck’ is to have the dollar bill act like the virtual arrow or the stage spotlight up on top of the rafters. It’s even better than the beige parchment envelope that I just spent time explaining about. However, if everything is to be understood in sequential order, then the envelope pointer theory did make its appearance before the ‘passing the buck theory.’
