When I teach a class, I always use pointers to show things on my slides.
Jokes aside, what pointers are you talking about? Code? Presentations?
Pointer are useful, since you don't have to copy some stuff around. It reduces the memory footprint, but you hace to watch out for parallel access on the same object.
It would be very helpful to discuss what language you’re using pointers in. Some languages use pointers under the hood, others don’t.
Yes all the time. Because I'm interested in the pointers targets.
