The class serves as the base class for all exceptions thrown to report errors presumably detectable before the program executes, such as violations of logical preconditions.
class logic_error : public exception {
public:
explicit logic_error(const string& message);
explicit logic_error(const char *message);
};The value returned by what() is a copy of message.data(). For more information, see what and data.
