Question

ASSIGNMENT - more on classesDue today A program needs a class to represent the date. 1. Define the year. Additionally, declare the following methods: class Date for this purpose using three integral data members for day, month, and void init( int month, int day, int year); void init(void); void print(void); Store the definition of the class Date in a header file Implement the methods for the class Date in a separate source file: 1. The method print0 outputs the date to standard output using the format Month- 2. The method init0 uses three parameters and copies the values passed to it to Day-Year corresponding members. A range check is not required at this stage, but will be added later. The method init0 without parameters writes the current date to the corresponding members. Note Use the functions declared in ctime 3. time_t time(time_t *ptrSec) struct tm *localtime(const time_t *ptrSec); The structure tm and sample calls to this function are included opposite. The type time_t is defined as long in ctime. The function time(0 returns the system time expressed as a number of seconds and writes this value to the variable referenced by ptrSec. This value can be passed to the function localtime() that converts the number of seconds to the local type tm date and returns a pointer to this structure. Test the class Date using an application program that once more is stored in a separate source file. To this end, define two objects for the class and display the current date.

Date.h

******************

class Date {

private:

int day, month, year;

public:

void init(int m, int d, int y);

void init(void);

void print(void);

};

Date.cpp

******************

#include <iostream>

#include <ctime>

#include "Date.h"

using namespace std;

void Date::init(int m, int d, int y) {

month = m;

day = d;

year = y;

}

void Date::init() {

time_t now = time(0);

tm *ltm = localtime(&now);

init(ltm->tm_mon + 1, ltm->tm_mday, 1970 + ltm->tm_year);

}

void Date::print() {

cout << month << "-" << day << "-" << year << endl;

}

Main.cpp

*****************

#include <iostream>

#include <ctime>

#include "Date.h"

using namespace std;

int main() {

Date d1;

d1.init();

d1.print();

Date d2;

d2.init(11, 30, 2017);

d2.print();

}
