I need to make an arrangement of size 10 objects within a different class, The only way I know how to do it is this:

(B is another class)

     class A
{
private:
    B arreglo[10];
public:
    A();
    A(string, int, B arreglo[10]);
};

The problem is I'm not entirely clear what the constructor should be by reference, how should I pass the fix to the constructor?

Could someone explain to me how? ...

Is there any way to handle it with pointers? ...

The problem is I'm not entirely clear what the constructor should be by reference, how should I pass the fix to the constructor?

The constructor by reference has this signature:

A(const A &referencia);

So your function:

A(string, int, B arreglo[10]);

It is NOT a constructor by reference. The fix is passed to the constructor when passing a reference to object A , said reference contains the arrangement with which you want to work. So, your constructor by reference could look something like this:

A::A(const A &referencia)
{
    std::copy(std::begin(referencia.arreglo), std::end(referencia.arreglo), std::begin(arreglo));
}

In the previous code, we copy the content of the arreglo belonging to the referencia in the referencia belonging to the object that is being built.
