What's the best way to trim std::string?

Question

I\'m currently using the following code to right-trim all the std::strings in my programs:

std::string s;
s.erase(s.find_last_not_of(\" \\n\\r\\         


        

Answer 1

Here's what I came up with:

std::stringstream trimmer;
trimmer << str;
trimmer >> str;

Stream extraction eliminates whitespace automatically, so this works like a charm.
Pretty clean and elegant too, if I do say so myself. ;)
