This advice about how to identify multiple classes within a single file applies only when your language restricts the number of files you can use in a program. If you re using C++, Java, Visual Basic or other languages that support multiple source files, put only one class in each file unless you have a compelling reason to do otherwise (such as including a few small classes that make up a single pattern). Within a single class, however, you might still have subgroups of routines, and you can group them using techniques such as the ones shown here.

Beyond the formatting techniques for routines is a larger formatting issue. How do you organize routines within a file, and how do you decide which routines to put in a file in the first place
Put one class in one file A file isn t just a bucket that holds some code. If your language allows it, a file should hold a collection of routines that supports one and only one purpose. A file reinforces the idea that a collection of routines are in the same class.

For details on the differences between classes and routines and how to make a collection of routines into a class, see 6, Working Classes.
All the routines within a file make up the class. The class might be one that the program really recognizes as such, or it might be just a logical entity that you ve created as part of your design. Classes are a semantic language concept. Files are a physical operating-system concept. The correspondence between classes and files is coincidental and continues to weaken over time as more environments support putting code into databases or otherwise obscuring the relationship between routines, classes, and files.
Give the file a name related to the class name Most projects have a one-to-one correspondence between class names and file names. A class named CustomerAccount would have files named CustomerAccount.cpp and CustomerAccount.h, for example. Separate routines within a file clearly Separate each routine from other routines with at least two blank lines. The blank lines are as effective as big rows of asterisks or dashes, and they re a lot easier to type and maintain. Use two or three to produce a visual difference between blank lines that are part of a routine and blank lines that separate routines. An example is shown in Listing 31-67:
Listing 31-67. Visual Basic example of using blank lines between routines.
'find the arithmetic maximum of arg1 and arg2 Function Max( arg1 As Integer, arg2 As Integer ) As Integer If ( arg1 > arg2 ) Then Max = arg1 Else Max = arg2 End If End Function
4 At least two blank lines separate the two routines.
'find the arithmetic minimum of arg1 and arg2 Function Min( arg1 As Integer, arg2 As Integer ) As Integer If ( arg1 < arg2 ) Then Min = arg1 Else Min = arg2 End If end Function
Blank lines are easier to type than any other kind of separator and look at least as good. Three blank lines are used here so that the separation between routines is more noticeable than the blank lines within each routine.

Sequence routines alphabetically An alternative to grouping related routines in a file is to put them in alphabetical order. If you can t break a program up into classes or if your editor doesn t allow you to find functions easily, the alphabetical approach can save search time. In C++, order the source file carefully Here s the standard order of source-file contents in C++:
File-description comment #include files Constant definitions Enums Macro function definitions Type definitions Global variables and functions imported Global variables and functions exported Variables and functions that are private to the file Classes
