Great job learning about structures! We’ve covered many important topics:

• Structures allow you to create user-defined data types
• Structures can package together other data types into one type
• You can define a structure using the struct keyword
• When defining a structure, the member variables are declared but not instantiated
• Structures help programs work with complex data and can represent real-world objects
• You can access member variables with the dot operator
• You can have a pointer to a structure and access its member variables using the arrow operator
• You can pass structures and structure pointers to functions
• You can return structures from functions

With our understanding of structures, we can now create and work with complicated data types easily and efficiently.
