使用文件中的提取运算符分隔行的空格 [英] Whitespace separating lines using extraction operator on file
问题描述
好的，我打开了一个文件，称之为infile。我有一个简单的时间（！eof），
但是说我的文件的第一行是<？xml version =" 1.0">，然后它获取
两次迭代来获取字符串。第一个''line''是"<？xml"，然后''line''是
" version =" 1.0""，我需要的是什么改变这样的行为，我可以得到文件中换行符分隔的行吗？
std :: string line;
std :: ifstream infile（&whatever.txt"，std :: ios_base :: in）;
while（！infile.eof（））
{
infile>> line;
std :: cout<< line<< std :: endl;
line ="" ;;
}
infile.close（）;
感谢您的时间，
Kevin Grigorenko
Okay, i''ve got a file open, call it infile. I''ve got a simple while(!eof),
but say the first line of my file is "<?xml version="1.0">", then it takes
two iterations to get the string. first ''line'' is "<?xml", then ''line'' is
"version="1.0"", what''s happening that I need to change the behavior of so
that I can get lines delimitted by the newlines in the file?
std::string line;
std::ifstream infile("whatever.txt", std::ios_base::in);
while(!infile.eof())
{
infile >> line;
std::cout << line << std::endl;
line = "";
}
infile.close();
Thanks for your time,

指出懒惰是好的，但你可以至少只是给了我
一些要看的部分。这个论坛上的每个问题都已在某个时间点在互联网上的某个地方得到回答，但搜索很痛苦
且乏味，这就是为什么人们会问同样的问题
新闻组中一遍又一遍的问题 - 它节省了时间。当我还是个孩子的时候，我没有时间，所以我试着在论坛中引起好心人的帮助。所以
请在将来不要只告诉别人那是在某处。
祝你好运。这是一个非常荒谬而明显的答案。
我会根据您的建议查看常见问题解答，并希望其他人
多一点同情将在该时间范围内回复并指向
a更多离散方向。

It''s fine to point out laziness, but you could have at minimum just given me
some section to look at. Every question on this forum has been answered
somewhere on the internet at some point in time, but searching is painful
and tedious, that''s why people ask the same questions over and over again in
newsgroups - it saves time. I don''t have the time I once had when I was a
teenager, so I try to elicit the help of the nice people in forums. So
please in the future do not just tell people "That is covered somewhere.
Good luck." That is a pretty ridiculous and obvious answer.
I will look at the FAQ as per your suggestion and hope that someone else
with a little bit more sympathy will reply in that timeframe and point me to
a more discrete direction.

所以我应该为你做这件事吗？

他们的时间。
我没有时间，当我还是青少年时，我没有时间，所以我试着在论坛中引起好人的帮助。所以

很明显，是的。荒谬，没有。

It''s fine to point out laziness I didn''t say that.

也许，我帮助的下一个人再也不会对我无礼了。
我不喜欢尽管如此，还是抱有很大希望。
再次，祝你好运。
巴斯特。
And just maybe, the next person I help won''t be gratuitously rude to me, again.
I don''t hold out much hope though.
Again, good luck.
