Write a program in PL/SQL to FETCH records with nested Cursors using Cursor FOR Loops

DECLARE
  emp_dept_id departments.department_id%TYPE;
 CURSOR cur_dept IS
  SELECT * 
  FROM departments
  WHERE manager_id IS NOT NULL
  ORDER BY department_name;
 CURSOR cur_emp IS
  SELECT * 
  FROM employees
  WHERE department_id = emp_dept_id;
  
BEGIN
    FOR r_dept IN cur_dept
    LOOP
      emp_dept_id := r_dept.department_id;
      DBMS_OUTPUT.PUT_LINE('----------------------------------');
      DBMS_OUTPUT.PUT_LINE('Department Name : '||r_dept.department_name);
      DBMS_OUTPUT.PUT_LINE('----------------------------------');
           FOR r_emp IN cur_emp 
           LOOP
             DBMS_OUTPUT.PUT_LINE('Employee: '||r_emp.last_name);
           END LOOP;   
    END LOOP;
END;
