Contents |
Parameters
| ch | - | character |
| loc | - | locale |
Return value
Returns true if the character is classified as punctuation, false otherwise.
Possible implementation
Example
Demonstrates the use of ispunct() with different locales (OS-specific).
Run this code
#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
