std::numpunct::~numpunct(3)

🌸 NAME 🌸

std::numpunct::~numpunct — that’s the name, bestie: std::numpunct::~numpunct. This page comes from the C++ Standard Libary manual (yes, “Libary” exactly like the header says — keeping it 💯).

🦋 Synopsis 🦋

Defined in header <locale>:

protected: ~numpunct();

Okay so this destructor destructs a std::numpunct facet. It’s protected and virtual — virtual because the base class destructor is virtual, iykyk. An object of type std::numpunct, like most facets, can only be destroyed when the last std::locale object that implements this facet goes out of scope, or if a user-defined class is derived from std::numpunct and implements a public destructor. That’s the whole vibe, no cap 💅.

🎀 Example 🎀

// Run this code

#include <iostream>
#include <locale>

struct Destructible_numpunct : public std::numpunct<wchar_t>
{
    Destructible_numpunct(std::size_t refs = 0) : numpunct(refs) {}
    // note: the implicit destructor is public
};

int main()
{
    Destructible_numpunct dc;
    // std::numpunct<wchar_t> c; // compile error: protected destructor
}
