Calculating the Difference Between Two Times

Calculating the Difference Between Two Times

When you need to compute the time that elapsed between two dates, use the standard function difftime(). This way, you avoid potential bugs such as leap years or Y2K issues. difftime() takes two variables of type time_t, each representing a date, and returns the number of seconds that elapsed between the two. For example:

 #include #include using namespace std;int main(){ time_t now = time(0); // get current time time_t last_week = now
