1. Cel ćwiczenia

Celem ćwiczenia jest zapoznanie się z obsługą C++ w środowisku Microsoft Visual C++.

2. Przykłady

Zad1

Przykład aplikacji logowanie, gdzie należy wpisać poprawny Login i Hasło aby dostać informację o wprowadzeniu prawidłowych danych. W przeciwnym wypadku dostaniemy komunikat iż wprowadzone przez nas dane są nieprawidłowe.

Zad2

Przykładowa aplikacja za zadanie ma wypisywać w polu tekstowym wyraz który został wpisany w pole Tekst z częstotliwością czasu jaki został ustawiony w polu Czas (przy czym wartości wpisana 3000 = 3 sekundy). Przycisk Start służy do uruchomienia działania aplikacji, Stop do zatrzymania a przycisk OK do ustawienia (akceptowania) wprowadzonego czasu.

Aby było widoczne działanie aplikacji, należy uruchomić edytor tekstu (np. notatnik) i po wystartowaniu aplikacji, ustawieniu czasu postawić kursor myszy na polu tekstowym edytora tekstu (kliknąć myszą w polu edytora).

3. Program ćwiczenia

Zad4

Należy wykonać aplikację która będzie wykonywać odpowiednie operacje przy wciśnięciu konkretnego przycisku. Czyli, jeden przycisk jest odpowiedzialny za operację dzielenia, drugi za operację dodawania a trzeci za operację odejmowania. Przy wyświetlanym wyniku należy dodać informację z jakieś operacji jest ten wynik. Aplikacja ma być również wyposażona w przycisk który będzie zamykał aplikację.

Poniżej zdjęcie aplikacji.

Zad5

Należy wykonać aplikację która będzie dodawała wartości heksadecymalne (szesnastkowe) i następnie konwertowało wynik do postaci dziesiętnej. Poniżej zdjęcie aplikacji.
