For some programs, these simple variables are enough. However, most programs need a way to bundle related data into a neat package.

As shown in Book I, C# provides arrays and other collections for gathering into one structure groups of like-typed variables, such as strings or ints. A hypothetical college, for example, might track its students by using an array. But a student is much more than just a name — how should this type of program represent a student?
