Structs,Structs are programmer-defined data types, very similar to classes. They have data members and function members. Although similar to classes, there are a number of important differences. The most important ones are the following:

Conversions,To get an understanding of what conversions are, let’s start by considering the simple case in which you declare two variables of different types and then assign the value of one (the .) to the other (the .). Before the assignment can occur, the source value must be converted to a value of the target type. Figure 18-1 illustrates type conversion.

Generics,With the language constructs you’ve learned so far, you can build powerful objects of many different types. You do this mostly by declaring classes that encapsulate the behavior you want and then creating instances of those classes.

Methods,o a method and receive data back as output. As you saw in the previous chapter, a method is a function member of a class. Methods have two major sections, as shown in Figure 5-1—the method header and the method body.
