我们如何估计程序完成所需的时间并将其反映到进度条上? [英] How can we estimate the time needed for program to complete and reflect that to progress bar?

问题描述

这不是特定于编程语言的.

This is not programming language specific.

我只需要了解如何估计完成流程所需的时间?例如解压缩文件或刻录CD?哪些因素会提高这种计算的准确性?

I just need to understand how can I estimate the time needed for a process to complete ? Such as unzipping file for example or burning a CD ? What are the factors that enhance the accuracy of this calculatio ?

任何编程语言中的一些示例当然会有所帮助.

Some examples in any programming language will help of course.

推荐答案

记录实际使用时间及相关因素；在类似情况下，根据过去运行的平均值估计未来时间.在大多数情况下，它永远不会那么准确，但我认为总比没有好.

Record the actual times taken and relevant factors; estimate future times based the averages of past runs with in similar situations. In most cases it will never be all that accurate, but it's better than nothing I suppose.

正如您所说，这不是特定于语言的，而是非常特定于情况的；与刻录光盘相关的因素可能与影响解压缩文件时间的因素不同.

As you say, this isn't language specific, but it is very situation specific; the factors that are relevant to burning a disc are probably different to the factors that influence the time to unzip a file.
