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

This can be done more simply in C++11 due to the addition of back() and pop_back().

while ( !s.empty() && isspace(s.back()) ) s.pop_back();
