someone please give a proper solution?

int new ( ); :-    behave as function prototype.
    new ( );    :-  function calling

(*new) ( );   :- function calling ......welcome welcome

P:- doesn't require function prototype before main every time...it is required only if function return type in not int.....

(*new) ( ) @hs_yadav can you explain it more how it can be a function calling.
