You can use std::string::erase
, which I personally find a little more clear semantically than the resize
alternative:
if (!s.empty())
s.erase (s.size()-1);
Pregunta
I'm using Visual C++ 2008. I can't use pop_back
because it became a member function of the string class in C++11.
What could I use instead since I can't use pop_back
?

You can use std::string::resize
:
if (!s.empty())
s.resize(s.size()-1);
I didn't quite understand your question but if you want to append something to a std::string you can use
and if you want to "shrink" it you can use
There are at least two possibilites. Either to use member function erase or member function resize. for example
s.erase( s.size() - 1 );
or
s.resize( s.size() - 1 );
If you do not want to use push_back then you can substitute it for operator + or member function append.
