PL/SQL code not working

Question

why is this code giving me error?
declare
type dept_tab_type is table of departments%rowtype;
index by binary_integer;
dept_tab dept_tab_type;
v_counter number(3):= 270;
begin
for i in 10..v_count
loop
select * into dept_tab(i)
from departments
end loop;
for i in dept_tab.first..dept_tab.last
loop
DBMS_OUTPUT.PUT_LINE(dept_tab(i).department_name);
end loop;
end;
i got this error
ORA-06550: line 3, column 5:
PLS-00103: Encountered the symbol "INDEX" when expecting one of the following:
begin function package pragma procedure subtype type use
<an identifier> <a double-quoted delimited-identifier> form
current cursor

Answer 1

I think its you DEPT_TAB_TYPE deceleration which was incorrect.
I think this might do it;
set serveroutput on
declare
  type dept_tab_type is table of departments%rowtype index by binary_integer;
  dept_tab dept_tab_type;
  v_counter number(3):= 270;
begin
  for i in 10..v_counter loop
    select *
    into dept_tab(i)
    from departments
  end loop;
  for i in dept_tab.first..dept_tab.last loop
    DBMS_OUTPUT.PUT_LINE(dept_tab(i).department_name);
  end loop;
end;
