When you say "execution time", do you mean the length of time the program is running on the system, or how much CPU time the program uses?

If you want total running time, just get the system date when the app starts and when it ends, and subtract them to get the toytal duration.

If you want CPU utilization...

almost 29 million google results for the search phrase "c determine cpu usage for an application" [^]
