Understanding Embedded C: What Are Structures?

Understanding Embedded C: What Are Structures?

After introducing structures, we’ll take a look at some of the important applications of this powerful data object. Then, we’ll examine the C language syntax to declare a structure. Finally, we’ll briefly introduce the data alignment requirement. We’ll see that we may be able to reduce the size of a structure by simply rearranging the order of its members.
