Once structure or union variables have been declared, members are referenced by specifying the variable name with the dot operator (.) or a pointer with the arrow operator (->) and the member name. For example, both of the following:
perm_address.prov = "Ontario";
p_perm_address -> prov = "Ontario";assign the string "Ontario" to the pointer prov that is in the structure perm_address.
All references to members of structures and unions, including bit fields, must be fully qualified. In the previous example, the fourth field cannot be referenced by prov alone, but only by perm_address.prov.
