Understanding structures

Like classes, structures also group together properties and methods used to represent an object and do specific tasks. Remember the Animal class you created? You can also use a structure to accomplish the same thing. There are differences between classes and structures though, and you will learn more about those later in this chapter.

Here’s what a structure declaration and definition look like:

struct StructName { 
   property1 
   property2 
   property3
   method1() {
      code
   }
   method2(){
      code
   }
}

As you can see, a structure is very similar to a class. It also has a descriptive name, can contain properties and methods, and you can create instances.
