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 is my version:

size_t beg = s.find_first_not_of(" \r\n");
return (beg == string::npos) ? "" : in.substr(beg, s.find_last_not_of(" \r\n") - beg);
