        cout<<"\t\t  destructor msg:object  "   <<countl<<"destroy....."<<endl;
          countl--;
    }
 };


 int main()
 {

     cout<<"inside block...."<<endl<<endl;
     cout<<"creat object....."<<endl;

    {


         test t1;


      {
         cout<<"inside main block.."<<endl;
          cout<<"creat another two  object....."<<endl;
          test t2,t3;
          cout<<"leave the block....."<<endl;
