Determine number of seconds since 1970 for both dates
Subtract smallest from largest number
divide by /60/60/24 for # days

example to get you started

6

8
9
10
11
12
13
#include <iostream>
#include <string>
#include <time.h>
using namespace std;

int main()
{
time (0);
cout << "Current time in Seconds from 1/1/1970 =  " << time (0)<<endl;
cout << "Current time in days from 1/1/1970    =  " << time (0)/60/60/24<<endl;

return 0;
}
