Detailed Description
       Base class for all library exceptions.

       This is the base class for all exceptions thrown by the standard
       library, and by certain language expressions. You are free to derive
       your own exception classes, or use a different hierarchy, or to throw
       non-class data (e.g., fundamental types).

Member Function Documentation
   virtual constexpr const char * std::exception::what () const [inline],
       [constexpr],  [virtual],  [noexcept]
       Returns a C-style character string describing the general cause of the
       current error.

       Reimplemented in std::bad_alloc, std::bad_cast, std::bad_exception,
