Wenn NDEBUG nicht definiert ist, dann assert prüft, ob ihr Argument (das muss skalar Art haben) vergleicht gleich Null. Ist dies der Fall, assert ausgibt Umsetzung Diagnose-Informationen über die Standard-Fehlerausgabe und ruft abort(). Die Diagnoseinformationen ist erforderlich, um den Text der expression sowie die Werte der Standard-Makros __FILE__, __LINE__, und die Standard-Variable __func__ gehören .
Original:
If NDEBUG is not defined, then assert checks if its argument (which must have scalar type) compares equal to zero. If it does, assert outputs implementation-specific diagnostic information on the standard error output and calls abort(). The diagnostic information is required to include the text of expression, as well as the values of the standard macros __FILE__, __LINE__, and the standard variable __func__.
