C + + Singleton mode

When you used a singleton pattern in a project, you prefer to use a static pointer implementation, but you need to release the contents of the pointer at the end of the program, or it will cause a memory leak, with the following code:

log& log::instance () {    if(NULL = = Ms_log    )        {staticnew Log ("./log.txt");         if (!ms_log->M_logout.good ())        {            "log file \"./log.txt\ "" << Std::endl;        }    }     return *ms_log;}

Today it is possible to use static objects to avoid this problem:

log& log::instance () {    static Log slog ("./log.txt");     if (! Slog.m_logout.good ())    {        "log file \"./log.txt\ "" << Std::endl;    }     return slog;}

All great thoughts and deeds have a trivial beginning.
