Notes

Die gets() Funktion führt keine Überprüfung der Grenzen, ist daher diese Funktion extrem anfällig für Buffer-Overflow-Attacken. Es kann nicht sicher verwendet werden (es sei denn, das Programm läuft in einem Umfeld, das, was man auf stdin erscheinen beschränkt). Aus diesem Grund wurde die Funktion in der dritten Berichtigung wurde der C99-Standard veraltet und ganz in der C11-Standard entfernt. fgets() und gets_s() sind die empfohlenen Ersatz .

Original:

The gets() function does not perform bounds checking, therefore this function is extremely vulnerable to buffer-overflow attacks. It cannot be used safely (unless the program runs in an environment which restricts what can appear on stdin). For this reason, the function has been deprecated in the third corrigendum to the C99 standard and removed altogether in the C11 standard. fgets() and gets_s() are the recommended replacements.
