membres statiques est spécialisations partielles de classes

[AG]

Bonjour,

voici mon bout de code (toujours le même en amélioré). Ma question est la
suivante :

combien de tableau tab ai-je ? Moi j'en veux que deux. Un pour myA1 et un
pour myA2. Le fait que je sois obligé de spécialiser l'instanciation du
tableau statique tab me fait penser que j'aurais 12 tableau en tout. Est-ce
bien ça ?

D'avance merci.

Alexandre.


#define D 5

const int L=10;

template <class T,bool S,int N=0> class A
{
static T tab[D*L];
A<T,S,N+1> next;
public:
void f(void)
{
for(int i=0;i<L;i++) tab[N*L+i+1]+=tab[N*L+i];
next.f();
};
};

template<class T,bool S> class A<T,S,D>
{
static T tab[D*L];
public:
void f(void)
{
for(int i=0;i<S;i++) tab[D*L+i+1]+=tab[D*L+i];
};
};


template<class T, bool S,int N>
T A<T,S,N>::tab[D*L]={0};

template<class T, bool S>
T A<T,S,D>::tab[D*L]={0};

int main(void)
{
A<int,true> myA1;
A<int,false> myA2
myA1.f();
myA2.f();
}

thank you Keith for the answer. I made a mystake sending my post.

No problem. Cancels typically don't work; they're not authenticated,
and forged cancels have caused most servers to ignore all cancels.

It did cancel on my newsgroup server. Just curious, do French speaking
newsgroups have grammatical standards?

no idea.

Cancels are done by sending a specially formatted article. Probably
your server accepted it and tried to pass it on to other servers, but
other servers ignored it.

The solution is to think before you post (a rule I don't always follow
myself).

I think you've managed to find *exactly* the wrong place to ask that
question. }
