Napisz program, który dla danej liczby A i B wyświetla następujący blok znaków.

Napisz program, który symuluje auto sterowane za pomocą poleceń konsoli. Program powinien posiadać następujące komendy:
+
+ Start — uruchamia auto
+ Stop — zatrzymuje auto
+ Koniec — kończy działanie programu
+ Pomoc — wyświetla pomoc z opisem poszczególnych komend
+
+
Program powinien umieć reagować na sytuacje wyjątkowe. Ponowne użycie komendy „Start” jeśli auto jest uruchomione wyświetla komunikat w stylu: „przecież już jadę ;)”. W przypadku polecenia „Stop” jeśli samochód już stoi zobaczymy komunikat w stylu „O co chodzi? Przecież stoję???”. W przypadku wydania nieznanej komendy należy wyświetlić komunikat w stylu „Nie znam tej komendy”. Program powinien działać w pętli, aż do wydania komendy „Koniec”.
