A pointer **is a variable that stores the memory address of another variable**. It allows direct manipulation of memory. Declaration and initialization of a pointer looks like this:

- `int`: specifies **the base type of the variable that the pointer will point to**. In this case, it's an integer;

- `*`: called **dereference** operator, returns **the value stored at the address** held by a pointer;

- `p_Name`: the name of the pointer variable. You can choose any valid variable name;

- `nullptr`:  is a keyword that represents a null pointer, indicating that it is **empty and doesn't point to anything**.



> Note
> 
> Commonly, pointers are named with a prefix `p_` as a naming convention **signifying that the variable is a pointer**.
