std::runtime_error::runtime_error(conststring&__arg)[explicit]
       Takes a character string describing the error.

       One of two subclasses of exception.

       Runtime errors represent problems outside the scope of a program; they cannot be easily predicted and can
       generally only be caught as the program executes.

virtualconstchar*std::runtime_error::what()const[virtual],[noexcept]
       Returns a C-style character string describing the general cause of the current error (the same string
       passed to the ctor).

       Reimplemented from std::exception.

       Reimplemented in std::filesystem::filesystem_error, and
       std::experimental::filesystem::v1::filesystem_error.
