Question

Assuming that a year has 365 days, write a class named DayOfYear that takes an integer representing a day of the year and translates it to a string consisting of the month followed by day of the month. For example, Day 2 would be January 2. Day 32 would be February 1. Day 365 would be December 31.

The constructor for the class should take as parameter an integer representing the day of the year, and the class should have a member function print() that prints the day in the month–day format. The class should have an integer member variable to represent the day and should have static member variables holding string objects that can be used to assist in the translation from the integer format to the month-day format. Test your class by inputting various integers representing days and printing out their representation in the month–day format.

I don't what is wrong with my code, could anyone help me solve this problem? Thanks a lot!

// This program is to

#include <iostream>

#include <string>

#include <iomanip>

using namespace std;

static unsigned int MONTH_DAY[] = { 31, 59, 90,

120, 151, 181,

212, 243, 273,

304, 334, 365};

static string MONTH_NAME[] = { "January", "February", "March",

"April", "May", "June",

"July", "August", "September",

"October", "November", "December"};

class DayOfYear

{

private:

unsigned int day;

public:

// Constructor

DayOfYear(unsigned int d = 0)

{ this -> day = d; }

static unsigned int MONTH_DAY[];

static string MONTH_NAME[];

void print()

{

unsigned int month = 0;

while (MONTH_DAY[month] < this -> day)

{

month ++;

}

unsigned int d = this -> day - MONTH_DAY[month];

cout << MONTH_DAY[month] << " " << d << endl;

}

};

int main()

{

unsigned int day;

const unsigned int FIRST_DAY = 1;

const unsigned int LAST_DAY = 365;

cout << "Please enter the day: " << day;

cin >> day;

while (day < FIRST_DAY || day > LAST_DAY)

{

cout << "Invalid, please re-enter: ";

cin >> day;

}

DayOfYear day_of_year(day);

day_of_year.print();

return 0;

}

Hi,

The problem has been resolved. Some changes has been done in already written code. Now the code is working find. I'm attaching the screenshot of running code with expected output and the changes in code have been marked in bold to identify. Please refer to the below image.

Screenshot:

You are defining "MONTH_DAY" and "MONTH_NAME" twice in code so i have removed one of them from "below Constructor define".

Code:

---------------------

#include <iostream>

#include <string>

#include <iomanip>

using namespace std;

static unsigned int MONTH_DAY[] = { 31, 59, 90, 120, 151, 181, 212, 243, 273, 304, 334, 365};

static string MONTH_NAME[] = { "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"};

class DayOfYear

{

private:

unsigned int day;

public:

// Constructor

DayOfYear(unsigned int d = 0)

{
this -> day = d;
}

void print()

{

unsigned int month = 0;
//cout<<"day: "<<day<<endl;
unsigned int daynew = day;

while (MONTH_DAY[month] < day)

{

month ++;

}
if(month!=0)
   daynew= daynew-MONTH_DAY[month-1];

cout<<MONTH_NAME[month]<<" "<<daynew<<"\n\n";

}

};

int main()

{

unsigned int day;

const unsigned int FIRST_DAY = 1;

const unsigned int LAST_DAY = 365;

cout << "Please enter the day: \n";

cin >> day;

while (day < FIRST_DAY || day > LAST_DAY)

{

cout << "Invalid, please re-enter: ";

cin >> day;

}

DayOfYear day_of_year(day);

day_of_year.print();

return 0;

}
