template< class charT > bool ispunct( charT ch, const std::locale& loc ) { return std::use_facet<std::ctype<charT>>(loc).is(std::ctype_base::punct, ch); } |
Demonstrates the use of ispunct() with different locales (OS-specific).
#include <iostream> #include <locale> int main() { const wchar_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'; }
Output:
isalpha('⅋', C locale) returned false isalpha('⅋', Unicode locale) returned true
