In C it also helps to think of it in the equivalent pointer form: p == &(p[0]) p[0] == *(p+0) p[1] == *(p+1) where p is a pointer to some arbitrary d

In C it also helps to think of it in the equivalent pointer form: p == &(p[0]) p[0] == *(p+0) p[1] == *(p+1) where p is a pointer to some arbitrary data type. Then it becomes an offset in memory.
