    Number(const int *x){
        i = new int[1];
        i = x;
    }
    Number(const Number &N){
        i = new int[1];
        i = N.i;
    }
    void getData(){
        cout<<&i<<endl;
    }
};
int main(){
    int x = 15;
    Number N1(&x), N2 = N1;
    N1.getData();
    N2.getData();
    return 0;
