| template< class charT > bool isgraph( charT ch, const locale& loc ); |
||
Checks if the given character classified as a graphic character (i.e. printable, excluding space) by the given locale's std::ctype facet.
Contents |
Parameters
| ch | - | character |
| loc | - | locale |
Return value
Returns true if the character is classified as graphic, false otherwise.
Possible implementation
template< class charT > bool isgraph( charT ch, const std::locale& loc ) { return std::use_facet<std::ctype<charT>>(loc).is(std::ctype_base::graph, ch); } |
Example
Demonstrates the use of isgraph() with different locales (OS-specific).
Run this code
#include <iostream> #include <locale> int main() { const wchar_t c = L'\u2a0c'; // quadruple integral std::locale loc1("C"); std::cout << "isgraph('⨌', C locale) returned " << std::boolalpha << std::isgraph(c, loc1) << '\n'; std::locale loc2("en_US.UTF-8"); std::cout << "isgraph('⨌', Unicode locale) returned " << std::boolalpha << std::isgraph(c, loc2) << '\n'; }
Output:
isgraph('⨌', C locale) returned false
isgraph('⨌', Unicode locale) returned true
