3.2 Efectul (aici, baza de sus a cubului se roteste in sens opus in comparative cu baza de jos):

4. Concluzie: n timpul efecturii acestei lucrri am facut cunostinta cu principiilede baza al lucrului cu ferestrele descendente. Am studiat functiile si procedurile

principale(EnableWindow, SendMessage,) care raspund de functionalitatea acestor ferestre.
