Remove last character from C++ string

Question

How can I remove last character from a C++ string?

I tried st = substr(st.length()-1); But it didn\'t work.

Answer 1

str.erase(str.begin() + str.size() - 1)

str.erase(str.rbegin()) does not compile unfortunately, since reverse_iterator cannot be converted to a normal_iterator.

C++11 is your friend in this case.
