      }

       int searching_element=0;
       int flag=0;

       cout<<"\n Enter the element you want to find  =  ";

      cout<<"\n The given element is found at the position  array["<<flag<<"].";

       else
      cout<<"\n The given element is not found.";

       getch( );
       return 0;
    }
