Logic errors represent problems in the internal logic of a program; in theory, these are preventable, and even detectable before the program runs (e.g., violations of class invariants).
|std::logic_error::logic_error||(||const string &||__arg||)||
Takes a character string describing the error.
|virtual const char* std::logic_error::what||(||)|| const throw ()
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.
