I have allowed this message through as a reply to a previous post, but material of this form is generally off-topic; please do not continue this thread unless topical material (i.e., material related to standardization of C++) is involved.

ls.erase(std::remove(ls.begin(), ls.end(), ','), ls.end())

This also works with other containers. It may seem weird, but it's the
ususal way of doing it in the STL.

You should get yourself a good book about the STL, because a reference
alone isn't enough; you need to know some idioms and concepts.

According to what you said,  i try it and it is ok,
thank you for your help and your advice.

and i try another algorithm remove as well. look like this,

string ls(" i , am , dog");

remove(ls.begin(), ls.end(), ',');

of course, i have used namespace std. and i get "i am dogog".
i traced into the function,and found that in fact it calls remove_copy.

I'll post an answer to comp.lang.c++, as this is off topic here and the
moderators are getting angry I think. :)
