# std::isgraph(std::locale)

From cppreference.com
< cpp‎ | locale

Defined in header `<locale>` |  |
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.

### [edit] Parameters

ch | - | character
loc | - | locale

### [edit] Return value

Returns true if the character is classified as graphic, false otherwise.

### [edit] 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);
    }

### [edit] 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
