Structures are value types. When we pass instances of a structure within our application, we pass a copy of the structure and not the original structure. Classes are reference types; therefore, when we pass an instance of a class within our application, a reference to the original instance is passed. It is very important to understand this difference. We will give a very high-level view here and will provide additional details in Chapter 16, Memory Management.When we pass structures within our application, we are passing copies of the structures and not the original structures. Since the function gets its own copy of the structure, it can change it as needed without affecting the original instance of the structure.When we pass an instance of a class within our application, we are passing a reference to the original instance of the class.
