    Notes

    La fonction gets() n'effectue pas la vérification des limites, par conséquent cette fonction est extrêmement vulnérable aux attaques par Buffer Overflow. Il ne peut pas être utilisé en toute sécurité (à moins que le programme s'exécute dans un environnement qui limite ce qui peut apparaître sur stdin). Pour cette raison, la fonction a été désapprouvée dans le corrigendum troisième à la norme C99 et enlevé tout à fait dans la norme C11. fgets() et gets_s() sont les remplacements recommandés .
    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.
