Witam.
Próbuję robić program, gdzie spadają mi wyrazy a ja mam wpisać odpowiedź. Na razie "a".
Niestety po dwóch wpisanych odpowiedziach program się blokuje.
Gdybym zwiększył ilość haseł, to jak zostaną 2 ostatnie, to program się zablokuje.
Jeżeli pozwoliłbym, żeby na ekranie było widoczne więcej haseł niż jedno, to wtedy program się nie zablokuje.
Co to może być?
