Below is my new code for this julian day program. I have fixed some of the errors I mentioned earlier. However, the day is still one short for the julian day and my conditional if statement seems to be the problem. I have tried a couple of ways to fix it. Any suggestions.

Thanks.

```
// Assignment #3, Programming I, Summer 2005
// Name: Darius Juan Bloomer
#include <iostream>
#include <string>
#include <cmath>
using namespace std;
long julian ( int year, int month, int day );
int main()
{
const long int julian_day = 2450000;
int year = 0;
int month = 0;
int day = 0;
int t_year = 0;
int t_month = 0;
int t_day = 0;
cout << " Enter a year, month, day ( ex. 1323 11 30 or -1400 8 11): ";
cin >> year;
cin >> month;
cin >> day;
cout << endl << endl;
long julian_date = julian( year, month, day);
cout << julian_date << endl;
cout << " What is today's date in the same format(ex. 2005 2 22): ";
cin >> t_year;
cin >> t_month;
cin >> t_day;
long today_date = julian( t_year, t_month, t_day);
long difference = today_date - julian_date;
cout << difference << endl << endl;
return 0;
}
long julian ( int year, int month, int day)
{
int j_year = year;
int j_month = month;
int j_day = day;
if ( j_year < 0)
j_year += 1;
if ( j_month > 2)
j_month += 1;
else
{
j_month += 13;
j_year -= 1;
}
long jul =static_cast<long>(floor(365.25 * j_year) + floor(30.6001 * j_month) + j_day + 1720995.0);
// if (j_year <= 1582) {
// if (j_month <= 10)
// if ( j_day < 15 )
if ( j_year < 1582 || ( j_year == 1582 && (j_month < 10 || ( j_month == 10 && j_day < 15))))
return jul;
else
{
int ja = static_cast<int>(0.01 * j_year);
jul += static_cast<int>(2 - ja + 0.25 * ja);
return jul;
}
}
