# std::numpunct::~numpunct

From cppreference.com
< cpp‎ | locale‎ | numpunct

Defined in header `<locale>` |  |
protected: ~numpunct(); |  |

Destructs a std::numpunct facet. This destructor is protected and virtual (due to base class destructor being virtual). 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.

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