Returnstrue if the character is classified as punctuation,false otherwise.
template<class CharT>bool ispunct(CharT ch,conststd::locale& loc){returnstd::use_facet<std::ctype<CharT>>(loc).is(std::ctype_base::punct, ch);} |
Demonstrates the use ofstd::ispunct() with different locales (OS-specific).
#include <iostream>#include <locale> int main(){constwchar_t c= L'\u214b';// upside-down ampersand std::locale loc1("C");std::cout<<"ispunct('⅋', C locale) returned "<<std::boolalpha<<std::ispunct(c, loc1)<<'\n'; std::locale loc2("en_US.UTF-8");std::cout<<"ispunct('⅋', Unicode locale) returned "<<std::boolalpha<<std::ispunct(c, loc2)<<'\n';}
Possible output:
isalpha('⅋', C locale) returned falseisalpha('⅋', Unicode locale) returned true| checks if a character is a punctuation character (function)[edit] | |
| checks if a wide character is a punctuation character (function)[edit] |
