Shortening a string

Heya, quick kind of silly question, what is the best way to shorten a string to get rid of asci characters below 90 for example?

If I have a string such as "funny?" or "ending!", and I want to convert it to only "funny" or "ending" (basically just filter out all symbles). What is the best way to go about doing that? Thanks much.

You can use the generic algorithm std::remove_if(), along with the erase() member function of std::string, or by setting the character at the iterator returned by remove_if() to '\0' for null terminated strings.
