It actually doesn't matter what the compiler is, you just have to link it against a decent libc library. I've had a look, but I can't seem to find a way of getting anything better than a second resolution. On a multitasking systems (i.e. I'm using Linux on a dual-processor machine, so I think I should be OK. -Charles Nov 14 '05 #4 P: n/a Charles M.

How To Find The Execution Time Of A C Program

This is a hack (it would be possible for precision to be higher than this method determines, and the result should probably be considered a worst case estimate) but it's better Search This Site.. So, i suppose, you will find this useful. #include #include int main(){ clock_t start = clock(); // Execuatable code clock_t stop = clock(); double elapsed = (double)(stop - start) Dijkstra's Algorithm finds the shortest path with the lower cost in a Graph .

A major strength of Reactis for C is its ability to immediately catch memory errors as they occur and to generate test inputs which are likely to trigger memory errors. i'm using the following code, but I get a ton of C2143 errors when I use this. I think I'll stick with CLOCKS_PER_SEC, since I don't really need that much precision for processes that take 28+ min. (in parallel over 4 processors) to run. :^) Watch out for Clocks_per_sec In C CLOCK_PROCESS_CPUTIME_ID might be what you need. –Lalaland Aug 27 '11 at 17:37 1 In a multi-threaded program on a multi-CPU machine, the CPU time for a process could be much
