What are pointers?

Pointers, point to memory addresses, pretty self explanatory.

1. Declare them with int *ptr;
2. Initialise them with ptr = &x
3. Dereference them (get the inner value) int val = *ptr
4. Create and delete memory with new and delete

How do you deal with pointers?

Cpp also provides some nice syntactic sugar to access variables through pointers easier.

Instead of

1. dereferencing the pointer and access a variable: (*ptr).x
2. You can just do ptr->x

Ain’t that nice!
