学习编程过程中遇到一个数学问题假定要构建一个圆形的池塘，其中喂养一些鱼。通过研究发现，必须保证该池塘的表面积为2平房英尺，才能确保每条鱼有6英寸长。本例需要确定池塘的直径，以确保有足够的空间 #include <iostream> #include <cmath> using std::cout; using std::cin; using std::sqrt; int main() { const double fish_factor=2.0/0.5; 请教这行是什么意思？？？？ const double inches_per_foot=12.0; const double pi=3.14159265; ``````````````````````````````````````` 我知道是因式转换，但不明白这样转换的目的，2.0和0.5是怎么来的？这道题的思路应当怎样想呢？？？？？？？？？在后面的程序中有一行用到它 double pond_area=fish_count*fish_length*fish_factor; 计算出池塘所需要的面积。

八卦英语阅读“What if a foreign girl has a chinese boyfriend Hello everyone, I happened to look through the internet, looking for some information about how love is seen in China between a foreign girl and a chinese guy. But actually no real information was found. In the opposite case, if the foreigner is a male willing to date a chinese girl I was able to read the most interesting things. I am an european girl that loves China and decided to study mandarin chinese in college. I've been an exchange student in the USA during high school so this year I thought: " It's time to go to China". Me and some other collegues decided to go together. Some of them went back to europe right away. To them, China was just too hard. Instead, even if difficult, I started to like this country more and more. So I met him. Chinese, of course. He had a lot of foreign friends. He was actually always sorrounded by foreigners. As friends, he introduced me to chinese culture and helped me with the language. But then, something changed and we started looking to eachother in another way. We are now happily involved in a relationship that amazingly works. We know we are different. Sometimes I can see his way of worring too much for me. His jealousy. The fear of what other people can think if I do something that a chinese girl would never do. Some other times, he is more western than me. We have many friends in common and he knows how it works in my culture. Many times I tell him I love China and want to stay here, but it will be impossible to me to be like a chinese girl. He smiles, says he knows and tells me he doesn't regret it. It doesn't metter. But the question is, how much a chinese man is going to give up a normal chinese relationship for a mixed one? I mean, I am european, independent and live by myself since I was 16 years old. What will I be expected to do talking about a possible chinese future? How love is seen in China has always been a really interesting topic to me. But I don't know anyone in my same situation. Always and just heard about chinese girls with foreign guys.

对陌上行的关注已经降低了很多了现在正在看《三体》科幻小说，推荐给大家，个人觉得很不错

你什么时候接触网络的我记得那时还没有QQ，也许是有QQ了只是我还不知道，1999年在网吧里上的网，几月份不记得，但那时是夏天是肯定的。登陆yhoo网站聊天，还是用那个聊天室的那一个类型。
