How to access any member of a structure?
To access any member of a structure, we use the member access operator (.). The member access operator is coded as a period between the structure variable name and the structure member that we wish to access. You would use the keyword struct to define variables of structure type. Structures as Function Arguments.
How are structures used to represent a record?
Structures are used to represent a record. Suppose you want to keep track of your books in a library.

How to get a pointer to a structure?
Like primitive types, we can have pointer to a structure. If we have a pointer to structure, members are accessed using arrow ( -> ) operator instead of the dot (.) operator. What is structure member alignment?
