If you look in time.h you will find that time_t when using dev c++ is just a
long int. And what it is, is the amount of seconds since 1970 some time.
If you read this page you will learn more.
http://rabbit.eng.miami.edu/info/functions/time.html
Why I use null is because that gives you the current time. I used the
modulus because that gives you the remainder in a division in this case it
would be 5 seconds. If you had 70 seconds it would return a remainder of 10
instead of 5.

Thanks. A couple questions:
1. Exactly what is the time_t object and what can you do with it?
2. Why, to get seconds, do you mod by 60 yet minutes you divide by 60?
3. Why do you pass null to the time function, and what does that time
function return?
Have a great day,
Alex
