A class whose number of instances that can be instantiated is limited to one is called a singleton class. Thus, at any given time only one instance can exist, no more.
The singleton design pattern is used whenever the design requires only one instance of a class. Some examples:.
Application classes. There should only be one application class. (Note: Please bear in mind, MFC class 'CWinApp' is not implemented as a singleton class).
Logger classes. For logging purposes of an application there is usually one logger instance required.
