There are no arguments to 'srand' that depend on a template parameter

anybody knows why ?

template<class T, int s> void Apprentissage<T, s>::apprendre_base(int k, double learning_rate) {
    int min=s-s;
    int max = s-1;
    srand(time(NULL));

    for (int i = 0; i < k; i++) {
        int rd= rand()%(max-min+1) + min;
        //  cout<<rd<<endl;
        T in(rd);
        n->apprentissage(in,learning_rate) ;
    }
}
