WebTo get the CPU time used by a task within a C application, use: clock_t begin = clock (); /* here, do your time-consuming job */ clock_t end = clock (); double time_spent = (double) (end - begin) / CLOCKS_PER_SEC; Note that this returns the time as a floating point type. This can be more precise than a second (e.g. you measure 4.52 seconds). Web描述. C 库函数 clock_t clock (void) 返回程序执行起（一般为程序的开头），处理器时钟所使用的时间。. 为了获取 CPU 所使用的秒数，您需要除以 CLOCKS_PER_SEC。. 在 32 位系统中，CLOCKS_PER_SEC 等于 1000000，该函数大约每 72 分钟会返回相同的值。.
