好吧，我不是专家关于STL，但这里有一些例子
例1：
char c;
while（your_istream。 get（c））
your_string.push_back（c）;
例2：
char c;
while（your_istream>> c）
your_string.push_back（c）;
例3：
string your_string;
while（your_istream>> your_string）
foo（）;

我害怕在某些时候制作副本是不可避免的。我希望你
可以调用reserve（），然后直接写入底层的
存储，就像vector一样 - 至少如果字符串从未出现过
复制。

I''m afraid making a copy at some point is unavoidable. I wish you
could call reserve() and then write directly into the underlying
storage, as with vector -- at least if the string had never been
copied.
