Fetching rows to display them is a task for the client tool. You need to define a ref cursor therefore.
If you just want to play around, here we go
SQL> DECLARE
  2    type t1 is table of emp%rowtype index by binary_integer;
  3    var1 t1;
  4    v_counter number:=0;
  5  BEGIN
  6    select * bulk collect into var1 from emp;
  7    for vr in 1..var1.count loop
  8      dbms_output.put_line(var1(vr).ename);
  9      update dept set deptno=var1.deptno Here also Error occured.
10    end loop;
11  END;
12  /
SCOTT

PL/SQL procedure successfully completed.
