std::isprint(std::locale)(3)

💖 std::isprint(std::locale)(3) 💖

okay so bestie, this is the std::isprint(std::locale)(3) page from the C++ Standard Libary — manual name folded in near the top, no cap. It's giving "does this character print?" energy and we're obsessed. 💅✨

🌸 NAME 🌸

std::isprint(std::locale) — std::isprint(std::locale)

Checks if the given character is classified as a printable character (including space) by the given locale's std::ctype facet.

✨ Synopsis ✨

Defined in header <locale>
template< class CharT >
bool isprint( CharT ch, const locale& loc );

💅 Parameters 💅

• ch — character
• loc — locale

🎀 Return value 🎀

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

🧚 Possible implementation 🧚

template<class CharT>
bool isprint(CharT ch, const std::locale& loc)
{
    return
std::use_facet<std::ctype<CharT>>(loc).is(std::ctype_base::print, ch);
}

🌈 Example 🌈

Demonstrates the use of isprint() with different locales (OS-specific).

The page literally says // Run this code, so here's the code, bestie:

#include <iostream>
#include <locale>

int main()
{
    const wchar_t c = L'\u2122'; // trademark sign

    std::locale loc1("C");
    std::cout << "isprint('™', C locale) returned "
              << std::boolalpha << std::isprint(c, loc1) << '\n';

    std::locale loc2("en_US.UTF-8");
    std::cout << "isprint('™', Unicode locale) returned "
              << std::boolalpha << std::isprint(c, loc2) << '\n';
}

⭐ Possible output ⭐

isprint('™', C locale) returned false
isprint('™', Unicode locale) returned true
