# std::num_put<CharT,OutputIt>::~num_put

From cppreference.com
< cpp‎ | locale‎ | num put

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

Destructs a std::num_put facet. This destructor is protected and virtual (due to base class destructor being virtual). An object of type std::num_put, 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::num_put and implements a public destructor.

### Example

Run this code

    #include <iostream>
    #include <locale>
    struct Destructible_num_put : public std::num_put<wchar_t>
    {
        Destructible_num_put(std::size_t refs = 0) : num_put(refs) {}
        // note: the implicit destructor is public
    };
    int main()
    {
        Destructible_num_put dc;
        // std::num_put<wchar_t> c;  // compile error: protected destructor
    }
