精确到达时间,以毫秒为单位 [英] getting elapsed time with accuracy in milliseconds
问题描述
我要求找到两个功能之间经过的时间
来电。我需要找到精确到1毫秒的时间。
我现在面临的问题是,我正在使用''时间()''
函数调用的目的,无论我多少次调用
我的程序中的函数,我得到相同的输出!!!
为了更好的清晰度考虑下面的代码片段。
I''ve a requirement to find the elapsed time between two function
calls. I need to find the time elapsed accurate to 1 millisecond.
The problem I''m facing right now is that, I''m using the ''time()''
function call for the purpose and regardless of how many time I invoke
the function within my program, I get the same output!!!
For better clarity consider the code snippet below.

因为time()只返回秒。
你必须使用clock(),它使用时钟滴答,你可以
转换为毫秒。

Because time() will only return seconds.
You will have to use clock(), which uses clock ticks, which you can
convert to milliseconds.

感谢你的准备时间()
而且,关于clock(),也得到了与tim相同的价值e()
每次我运行它!!!

Thanks for the heads up on time()
And, regarding clock(), also gets me the same value like that of time()
every time I run it!!!
