c - 测量耗时

Question

我添加了以下代码来测量以了解程序持续了多少毫秒。问题是我得到 1065 个时钟和 1065 毫秒。他们平等正常吗？也许我的将时钟转换为毫秒的方程式是错误的？提前致谢

finishClock = clock();
timeCount = finishClock - startClock ;
printf("Clocks passed: %f\n Milli Seconds passed: %f",timeCount, timeCount*1000/CLOCKS_PER_SEC);

Answer 1

基于 Tcl 引用 here ，它们是同义词:

If the -option argument is -milliseconds, then the command is synonymous with clock milliseconds (see below). This usage is obsolete, and clock milliseconds is to be considered the preferred way of obtaining a count of milliseconds.
