       In C++, how do I statically assert the type of a null-terminated string literal ("ordinary string literal", [lex.string])? 🙏For example, "it" whose type AFAIK is const char[3]static_assert(std::same_as<decltype("it"), const char[3]>); //failsCE: https://sigcpp.godbolt.org/z/4h475oh7a#question #cpp #cPlusPlus #programming

       @smurthys static_assert(std::same_as<decltype("it"), const char(&)[3]>);but it doesn't guarantee null termination

       @vitaut Good to know. But still type of "it" is const char[3], correct?

       @smurthys @vitaut Yes; decltype returns T& for lvalues (when the argument isn't an identifier or class member) which string literals are.
