Date Codes 1
Date nur Tag¶
aus mbed-Simulator
und Intro
Copy-Paste die folgenden Codes
#include "mbed.h" class Date // nur day implementiert; TODO: month and year { private: uint8_t day; public: Date():day(1) // Initialisierungsliste mit konstantem Parameterwert {} // Initialisierungsliste über parametrisierten Konstruktor Date(uint8_t _day):day(_day) { // entspircht: day = _day; .... siehe unten } Date(uint8_t _day, int _tmp) { day = _day; } ~Date() { printf("Good bye\n"); } // Destruktor uint8_t GetDay(); // Prototyping }; uint8_t Date::GetDay() { return day; } int main() { Date date1; // Instanziierung mit Standard Konstruktor und Date date2(18); // mit parametrisierten Konstruktor Date date3(30, 0); // mit parametrisierten Konstruktor printf("GetDay Test\n"); printf("Day 1: %d\n", date1.GetDay()); printf("Day 2: %d\n", date2.GetDay()); printf("Day 3: %d\n", date3.GetDay()); return 0; }
Tag, Monat, Jahr¶
