I've done pointers on C++ for a while but i've never got the idea of it.
Could you please explain Pointers to me?
What they do... Although i know that it points to an address on the memory but i don't really get it.

a pointer is a 32/64-bit value representing another address
that address is the start address of a block of memory containing all kinds of data from normal variables to other pointers

you can think about a pointer as an identifier to some type of data, a type of handle. we also call this type of identifier a 'reference'. it just so happens that this 'reference' has a value that corresponds to the virtual memory address of the data it is referencing

Lets say your scanning a pointer for your dynamic address which is 0x1000;

Your subtract the address your searching for by your offset range, then, do a range scan for any address whose value equals to any address in between that range ( address - offset range to address ).

imo one of the best ways to "get it" is to play around with them in the debugger.

it's easier to understand exactly what is happening when you can visually see it.
