remove char from stringstream and append some data

Question

In my code there is a loop that adds sth like that \"number,\" to stringstream. When it ends, I need to extract \',\' add \'}\' and add \'{\' if the loop is to repeated.

Answer 1

I've found this way using pop_back() string's method since c++11. Probably not so good as smarter ones above, but useful in much more complicated cases and/or for lazy people.
