Anyone explain on initializing each vector argument ?

One outright understand definitely each vector argument in initialization (v) ?

Code:

enum Mon : int {
A = 5,
B, C
};

struct M {

explicit M(Mon m, Mon n) : v{ 1, m } {}
vector<Mon> v;
};


int main(){
Mon m=A, n=B;

M moo{m, n};

}

the first; 1 ?

Thanks before

It is suboptimal as parameter `n` is never used. Another attempt:

Code:

vector<Mon> *genMonVect(Mon m, Mon n) {
  vector<Mon> *v= new vector<Mon>(m-n+1);
  for (Mon i=m; i<=n; ++i) v->push_back(i);
  return v;
}

int main() {
    vector<Mon> *v= genMonVect(Mon::B, Mon::C);
    ...
}
