nawet resultDestruktor nie zadzwonil, jak to rozwiazac? bo chcialbym zeby to bylo zapetlone a nie chce zeby doszlo do memory leaku, no i nawet jak to nie jest zapetlone to nie dziala tak jakbym chcial, bo program najpierw maze ekran konsoli a potem dopiero wywoluja sie te ostatnie destruktory, jak dam system("cls") do destruktora Result to nawet nie maze ekranu bo sie nie wywoluje ;p
