No periods, commas, if, ands, and buts. Literally I have a list of the most common words used in English and I also want to strip those too but I think I know how to do that and don't need a regular expression because it would be really way to long. How do I strip everything from a chunk of text except words that are

问题 There is a very useful function in Python called strip(). Any similar ones in C++? 回答1: There's nothing built-in; I used to use something like the following: template <std::ctype_base::mask mask> class IsNot { std::locale myLocale; // To ensure lifetime of facet... std::ctype<char> const* myCType; public: IsNot( std::locale const& l = std::locale() ) : myLocale( l ) , myCType( &std::use_facet<std::ctype<char> >( l ) ) { } bool operator()( char ch ) const { return ! myCType->is( mask, ch ); }
