Method of use

The functions start(), stop(), and clear() are used to start, stop and clear a Timer. The functions clock_time(), cpu_time(), user_time(), and system_time() are used to report the current values of a Timer.

As example, to time both the total time to complete a loop and each iteration of the loop, the following code could be used:

 
 		 Timer total_time; \+

 Timer iter_time;

 total_time.start(); 

 while ( . . .) 

 {  \+

 iter_time.start(); 

 . . . 

 iter_time.stop(); 

 printf("ITERATION TOOK %f seconds  n", iter_time.clock_time()); 

 iter_time.clear(); 

 } 

 total_time.stop();

 printf("TOTAL TIME %f seconds  n", total_time.clock_time());
