Answer 1

Do you want a column header in the output? If so you could do something like this:
BEGIN
        DBMS_OUTPUT.PUT_LINE('DEPTNO LOC');
        FOR D_DEPT_DETAILS IN (SELECT DEPTNO , LOC FROM DEPT)
        LOOP
                DBMS_OUTPUT.PUT_LINE(D_DEPT_DETAILS.DEPTNO || '      ' || D_DEPT_DETAILS.LOC);
        END LOOP;
END;
