Hey all, teaching myself CPP through a few books (and a little bit of CS in general through CS50) and hit a road block.

I understand what pointers are, and understand they’re a big part of programming. My question is why?

What do you use pointers for? Why is forwarding to a new memory address preferable to just changing the variable/replacing what’s already at the memory address or at a new one? Is it because new data could exceed the size of that address already allocated?

Thanks in advance!

    Ton of thanks for all the replies and examples. Some of it is over my head at the moment but most of it has shed some light none of the self-teach material has gotten into, I appreciate that.

    Letting this all sink then hitting the books again!
