"Wędrówka do źródła kodu" Popularna definicja programowania określa je jako "proces projektowania, tworzenia, testowania i utrzymywania kodu źródłowego programów komputerowych lub urządzeń mikroprocesorowych". Wspomniany kod źródłowy może być napisany w różnych językach programowania, z użyciem określonych reguł. Każdy z języków pozwala na wykorzystanie odpowiednich stylów programowania, a wybór konkretnego języka może zależeć od indywidualnych upodobań, polityki firmy lub funkcji, jakie końcowa aplikacja ma realizować. W zasadzie nie istnieje odpowiedź na pytanie, który z języków jest najlepszy. Dlatego w tej książce nie znajdziesz typowego abecadła. Zapoznasz się za to z danym problemem, a następnie programem komputerowym służącym do jego rozwiązania. Jeśli chcesz wreszcie rozpocząć przygodę z programowaniem i nawiązać dialog ze swoim komputerem, ta publikacja jest właśnie dla Ciebie! Różnorodne obliczenia, mniej lub bardziej skomplikowane, znane Ci z lekcji matematyki lub nieznacznie wykraczające poza program nauczania, stanowią tutaj podstawę do zdobywania informacji na temat programowania w wybranych językach. Wybrane zadania zaprezentowane są w popularnych językach programowania: Pascal, C i C++. Stosowane algorytmy wymagają także sięgnięcia po różne funkcje matematyczne, dostępne standardowo w bibliotekach języków programowania oraz konstruowane na podstawie wzorów. Zostań informatycznym poliglotą. Programuj każdego dnia!
