推荐答案

当然，由于您正在学习编程课程(并且正在上大学)，所以我假设您确实知道如何计算平均.如果没有，我建议 http://www.dtc.dla.mil/qa/Calcaverages .htm

您拥有所需的所有数据.计算平均值很容易.

Of course, Since you are in a programming course (and in college), I would assume you DO know how to calculate an average. If not, I would suggest http://www.dtc.dla.mil/qa/Calcaverages.htm

You have all the data you need. calculating the average is easy.
