This is a lot like programming, because you mainly have calculations going on around in the background of your code, then bam! You hit some delicate areas that need to be reported either to the screen or on paper. That pointer is like a doorbell to a queue of information waiting to be printed or read on the screen.
It’s true that the pointer notation is needed in the background code itself, but the processes done to the data are often custom-written and it’s sole purpose is for an interactive presentation with an audience. So like with straight pins, you might invest in keeping tabs on what needs to be hand-sewn, or in the case of pointers, what needs to be customized and appropriated memory to.
