I wonder what programming was like back in the early days like when Steve Wozniak and Steve Jobs were beginning the computer revolution! These iterators like pointers is really awesome! And it is so cool that we can utilize different analogies for them! One that our textbook that I really loved is that a stack could be seen like a PE dispenser! The last one you put in is also the first one to come out as you said, and it really helps someone who doesn't learn with coal too well hopefully understand all of this intricate lingo. It can be definitely hard to understand sometimes and I know that I've struggled with it from time to time. What do you think about all of this! Have you had a hard time understanding?
