Pointers and why



So I have been reading and get the logic with how to use pointers (except for some complicated implementations like void pointers) but I was trying to grasp the why and this line I found cleared it up for me:

If you happen to have a huge piece of data that you want to pass into a function, it’s a lot easier to pass its location to the function than to copy every element of the data!


It expands on it more but I figured that would help out some others that are new to this.
