class Test
{
 public:
      Test()
         {
        cout<<"constructor invoked"<<endl;
          }
     ~Test()
         {
        cout<<"Destructor invoked"<<endl;

{
cout<<"main begins";

}



Output:
constructor invoked//for t1
main begins
constructor invoked//for t2
block begins
constructor invoked//for t3
block ends
Destructor invoked//for t3
main ends
Destructor invoked//for t2
Destructor invoked//for t1
