Help understanding pointers

Question

Please help it doesn't make sense to me

Answer 1

On modern operating systems, programs are typically split into virtual memory pages, typically 4096 bytes long. It allows for having protected memory regions and not having all of a program loaded into physical memory at once or having to be in a contiguous part of ram. It also has the advantages of avoiding external fragmentation and easy page look ups for converting virtual addresses to physical addresses.

Answer 2

@Jordan Chapman Not just variables though, they can point to other things such as pages, functions, and modules

Answer 3

thanks, I'll have to look into that

Answer 4

a pointer just holds the memory location of a variable. You will get into more uses for pointers later in the course.

also, just a warning: don't use capse lock for posts. It's against guidelines and these guys don't like it

Answer 5

ahh, my bad. What do you mean by pages though?
