Identify the errors and re‐write the correct code:
set serveroutput on
c_id CUSTOMER.cust_id%Type;
t TOWNHOUSE.house_num%Type;
m_name MATERIALS.material_name%Type;
cursor info is
select cu.cust_id, t.house_num, m.material_name
from CUSTOMER cu, TOWNHOUSE t, MATERIALS m, PURCHASE_AGREEMENT pa
where cu.cust_id = pa.cust_id
and t.house_num = pa.house_num
and m.material_id = pa.material_id
begin
for rec in info
c_id:=rec.cust_id;
t:= rec.house_num;

dbms_output_put_line('CUSTOMER ID: ' || c_id || ', ' || chr(13) ||'HOUSE NUM: ' || t ||
