Witam,
Czy ktoś z Was mógłby sprawdzić czy dobrze wykonałem 3 zadania, które znajdują się pdfie?
Wszystko polecenia wykonałem (tak, wszystko ma się odbywać w jednym programie), jednak nie jestem do końca pewien czy dobrze zrozumiałem treść poleceń.
Chodzi mi tylko o potwierdzenie poprawności napisanego programu bądź wskazanie nad czym powinienem jeszcze popracować.
Z góry dzięki za jakąkolwiek pomoc :)
