Hope this helps..
DECLARE
  TYPE strarray IS TABLE OF VARCHAR2(100);
  p_empnames STRARRAY;
  v_tot INTEGER :=0;
  v_cnt INTEGER := 0;
BEGIN
  p_empnames := strarray('Allen','Smith');
  FOR i IN p_empnames.FIRST .. p_empnames.LAST LOOP
      SELECT COUNT(*) INTO v_tot FROM emp WHERE ename = p_empnames(i);
      v_cnt := v_cnt + v_tot;
  END LOOP; 
  DBMS_OUTPUT.PUT_LINE('Count '||v_cnt);
END;
Count 2
