Related to pointers

#1

list l;
auto it=l.begin();

it++; //how is this working ,as the memory is not linear
contiguous like in array

it=it+2; //but this is not working why

But in pointers this works like

int* ptr;
ptr=ptr+2;

#2

Hey @Gurjot

This is so because it is an iterator and ptr is a pointer , there is a difference between the two.
Iterator only knows about where to go next(like linked list) but in case of pointer since memory is linear it can be incremented by +k where k is whole number.

I hope your doubt is resolved now .:slight_smile:
