#include <iostream>
using namespace std;

int main ()

{
int days [12] = {31,28,31,30,31,30,31,31,30,31,30,31};
int difference;
int fmonth;
int fdate;
int smonth;
int sdate;

cout << "Enter your first Month and Date: " << endl;
cin >> fmonth >> fdate;
cout << "Enter your second Month and Date: " << endl;
cin >> smonth >> sdate;

difference = (days [fmonth - 1] - fdate);

cout << difference << " days between the dates. " << endl;

return 0;
}

My computer crashes on this line

difference = (days [fmonth - 1] - fdate);

what is wrong is that I have it set to nothing.

The point of this project is to calculate the number of days that the user enters when they enter a month and a date twice.

You understand?

Although I don't understand what this line shall accomplish, the pogra works for me. You might be giving it wrong input. Valid would be for example:
3 12
7 25

Then fmonth would be 3, fdate 12, smonth 7 and sdate 25.

If you want the day difference between two dates, here is a working program (yours a little bit modified)

Code:

---

int main ()
{
int days [12] = {31,28,31,30,31,30,31,31,30,31,30,31};
int difference;
int fmonth;
int fdate;
int fdays = 0;
int smonth;
int sdate;
int sdays = 0;
int i;

cout << "Enter your first Month and Date: " << endl;
cin >> fmonth >> fdate;
cout << "Enter your second Month and Date: " << endl;
cin >> smonth >> sdate;

for(i = 0; i < fmonth-1; i++)
        fdays += days[i];
fdays += fdate;

for(i = 0; i < smonth-1; i++)
        sdays += days[i];
sdays += sdate;

difference = (sdays - fdays);

cout << difference << " days between the dates. " << endl;

return 0;
}
