Strange output for class

Hi this code works and compiles without errors, the outptut is correct, but
under the date, I am getting a weird set of numbers. I think it has somthing
to do with the displayDate() function, but I am not sure. Do you know what is causing it?

Code:

#include <iostream>

using std::cout;
using std::endl;
using std::cin;

class Date
{
public:
   Date( int tempDay, int tempMonth, int tempYear )
   {
 		// check that number in constructor is not below zero
      if ( tempDay < 0 )
      {
         tempDay = 0;
      }
      
      day = tempDay;
      
      if ( tempMonth < 0 )
      {
         tempMonth = 0;
      }
      
      month = tempMonth;
      
      if ( tempYear < 0 )
      {
         tempYear = 0;
      }
      
      year = tempYear;
   }
   
   int setDay ( int d )
   {
      day = d;
   }
   
   int setMonth ( int m )
   {
      month = m;
   }
   
   int setYear ( int y )
   {
      year = y;
   }
   
   int getDay()
   {
      return day;
   }
   
   int getMonth()
   {
      return month;
   }
   
   int getYear()
   {
      return year;
   }
   
   int displayDate ( void )
   {
      cout << "\nDATE: " << day << " / " << month << " / " << year << endl;
   }
		 
private:
   int day;
   int month;
   int year;
};

// main function - driver //////////////////////////////////////////////////////
//
int main ( void )
{
   Date d ( 0, 0, 0 );
   
   // set values of members and display to screen
   d.setDay(5);
   cout << "Day is: " << d.getDay() << endl;
   d.setMonth(11);
   cout << "Month is: " << d.getMonth() << endl;
   d.setYear(2006);
   cout << "Year is: " << d.getYear() << endl;
   
   // display date in correct fromat
   cout << d.displayDate();
   
   cin.get();  // freeze console window
    
   return 0;   // indicate program ended sucsessfuly
}

Output I get:

Day is: 5
Month is: 11
Year is: 2006

Year is: 5 / 11 / 2006
457000 // this number should not be here!!

Exact console output please. Your dispplaydate and what you said it printed don't work

Code:

cout << "\nDATE: " << day << " / " << month << " / " << year << endl;

Year is: 5 / 11 / 2006 vs.
DATE is: 5 / 11 / 2006

Lol sorry I not checking the output:

This is the correct one:

Day is: 5
Month is: 11
Year is: 2006

DATE: 5 / 11 / 2006
4473856

Code:

int displayDate ( void )
   {
      cout << "\nDATE: " << day << " / " << month << " / " << year << endl;
   }

This function returns an int. As you don't state what int it should return, I guess it just returns a random value.

Code:

cout << d.displayDate();

This line displays the undefined return value of displayDate.

Solution: displayDate, and all your setter functions should return void. Whole date should be displayed using d.displayDate().

Thanks anon, I fixed it. I thought it was somthing simple. Many thanks for your help
