time the code

Question posted by: eternalLearner (Newbie) on June 3rd, 2008 05:35 AM

hi ,
i need to calculate the actual running time of my code .
that is i don't want the time wen my application is swapped out of the memory to show up in the time of the program,which actually happens wen i use the following :

Expand|Select|Wrap|Line Numbers

	
time_t initialtime;

time_t finaltime;

(void)time(&initialtime);
 
//do something 
 
(void)time(&finaltime);//end of the time
 
int time_taken  = finaltime - initialtime;

please let me know if there is any other way to time the program,so the constraint i have specified is taken care of.
thanks in advance.

Try using time <your executable> from command promt if u are running this in Unix.
I hope this will give the required info

Re: time the code

you can use, for example, Boost Timer Library. more info here:
