Question

Write a C++ Program.

You have a following class as a header file (dayType.h) and main().

#ifndef H_dayType

#define H_dayType

#include <string>

using namespace std;

class dayType

{

public:

    static string weekDays[7];

    void print() const;

    string nextDay() const;

    string prevDay() const;

    void addDay(int nDays);

    void setDay(string d);

    string getDay() const;

    dayType();

    dayType(string d);

private:

    string weekDay;

};

#endif

/*

// Name: Your Name

// ID: Your ID

*/

#include <iostream>

#include <string>

#include "dayType.h"

using namespace std;

int main()

{

    dayType myDay("Monday");

    dayType temp("Sunday");

    myDay.print();

    cout << endl;

    cout << myDay.prevDay() << endl;

    cout << myDay.nextDay() << endl;

    temp.print();

    cout << endl;

    cout << temp.prevDay() << endl;

    cout << temp.nextDay() << endl;

    return 0;

}

The class dayType should store the day, such as Sun for Sunday. The program should be able to perform the following operations on an object of type dayType:

1. Set the day
2. Print the day.
3. Return the day.
4. Return the next day.
5. Return the previous day.

Write the definitions of the functions to implement the operations for the class dayType as follows:

#include <iostream>

#include <string>

#include "dayType.h"  

using namespace std;

string dayType::weekDays[7] = {"Sunday", "Monday", "Tuesday",

                     "Wednesday", "Thursday", "Friday", "Saturday"};

void dayType::print() const

{

    cout << weekDay;

}

…

Your code here

….

dayType::dayType(string d)

{

    weekDay = d;

}

and then you MUST test various operations on this class using the main(). For example, if the current day is Monday and we add 4 days, the day to be returned is Friday. Similarly, if today is Tuesday and we add 13 days, the day to be returned is Monday.
