Member access operators allow access to the members of their operands.

Operator	Operator name	Example	Description
[]	array subscript	a[b]	access the bth element of array a
*	pointer dereference	*a	dereference the pointer a to access the data it points to
&	address of	&a	the address of a
.	struct member	a.b	access member b of struct a
->	struct member of pointer to struct	a->b	access member b of struct pointed to by a equivalent of first dereferencing the pointer to the struct a then accessing member b: (*a).b
