Can someone help to understand pointers when they used with structures. Thanks

Table 11-3 Expression Description s is a structure pointer and m is a member. This expression accesses the m member of the structure pointed to by s. a is a structure variable and p, a pointer, is a member. This expression dereferences the value pointed to by p. s is a structure pointer and m is a member. The * operator dereferences s, causing the expression to access the m member of the structure pointed to by s. This expression is the same as s->m . S->m s is a structure pointer and p, a pointer, is a member of the structure pointed to by s. This expression accesses the value pointed to by p. (The ->operator dereferences s and the * operator dereferences p.) s is a structure pointer and p, a pointer, is a member of the structure pointed to by s. This expression accesses the value pointed to by p. (*s) dereferences s and thd outermost operator dereferences p. The expression s->p is equivalent. *s->p
