expected primary expression before "." token

Hi there, I'm trying to do a program that allows user to enter a number between 1-365 and convert that to month and day (for example, 32 -> Feb. 1st). I tried compiling the program but I got "expected primary expression before '.' token" in int main(). I can't seem to figure out what I did wrong. If any of you can just point me in the right direction, that'll be awesome. Thank you so much!

Code:

//This program is for chapter 14 - review question 2 - Day of the year

#include <iostream>
#include <string>
using namespace std;

class DayOfYear
{
      private:
             static const int daysAtEnd[];
             static const int monthNames[];
      public:
             

void DayOfYear::print()
{
     int month = 0;
     int day;
     
     while (daysAtEnd[month] < day)
     month = (month+1)%12;
     if (month == 0)
     cout << "January" << day;
     else
     {
         cout << DayOfYear::monthNames[month]<< " "
         <<day - DayOfYear::monthNames[month-1];
     }
}

void DayOfYear::setNumber(int n)
{
     int number;
     if (n >= 0 && n <= 365)
     number=n;
     else
     {
         cout << n << "is not a valid"
         << "value for the month.\n";
         exit (EXIT_FAILURE);
     }
}

};

int daysAtEnd[12] = {31, 59, 90, 120, 151, 181, 212, 243, 273, 304, 334, 365};
char monthNames[] = "January, February, March, April, May, June, July, August, September, October, November, December";
   
int main()
{ 
    
DayOfYear.print(); <--- expected primary expression before "." token


system("PAUSE");
return 0;
}

thanks!!

At a glance, you need a DayOfYear object. Beyond that, you might want to switch books, perhaps based on the recommendations in What is the best book for a beginner to learn c++, if that code was from a beginners' book. It appears to be teaching the use of classes where the class is used rather poorly.

Basically, the DayOfYear class is like a cookie cutter, you need to make some cookies with the cutter before you can do anything.

Code:

//doy is the object or the "cookie" in the above analogy.
DayOfYear doy;

// calls the print method
doy.print();

There are a lot of things that are done poorly in that program. You should get a good book if you want to lean C.

What exactly do you want DayOfYear.print() to do?

You blew the analogy at the end. You should had said "the DayOfYear class is like a cookie cutter, you need to make some cookies with the cutter before you can eat them."

Especially since using an object is often referred to as "consuming" them.
