Singleton class has only one instance, and to provide a global point of access to it.

ex

class Singleton
  {
  public:
      static Singleton* Instance();
  protected:
      Singleton();
      Singleton(const Singleton&);
      Singleton& operator= (const Singleton&);
  private:
      static Singleton* pinstance;
  };
