I learned pointers by drawing boxes and arrows which I think is the best high-level explanation. Basically a variable is a container which holds a value from a predetermined set of values (also known as a type). For instance, an integer variable x holding the value 37 can be visualized as a box with the name x: x +--+ |37| +--+ A pointer variable p can be visualized as a box which "contains" an arrow pointing to another variable of a certain type, for instance p x +--+ +--+ | -|--->|37| +--+ +--+ which correspond to the C declarations int x = 37; int *p = &x;
