Question

At first I get a time by

time_t t1 = time(0) 

(is it right for getting current time?)
then

time_t t2 = time(0)

now I want the find the difference between t1 and t2 in milliseconds
I searched a lot but it didn’t worked.
lots of casting problems and unable to change it to milliseconds
thanks for your help in advance

Answer 1

Use difftime:

double diff = difftime(t2, t1);

This gives you the difference in seconds. Multiply diff by 1000 to get milliseconds.
