Question du test C - Les bases

Quelle est la taille d'un long long en C++?

Facile

En C, sachant que sur la machine ou exécute le code suivant un long pèse 8 octets, un char 1 octet et un short 2 octets, donnez la taille en octet de la structure suivante (1 seule bonne réponse) :

struct t {
 long z;
 union U {
    long a;
    char b;
    long c;
 }u;
};

Actually the alignement in memory isn't as precise as the anwsers, it depends of the memory layout and compiler. The compiler may add padding for alignment requirements.

Hello Nicolas, I'm sorry for that. Did you experienced the same problem on another question ?

Yes, it happened for every question. I found out that it did select my answer but my answer wasn't checked so I couldn't know what was selected. Everything else was working fine.
