Initialize static array in C++ as a range

Question

I have the following code:

template <int Size>
    class A
    {
        public: 
            static int size;
            static int myArray[Size];
    };

The size variable I can set by:

template <int Size>
int A<Size>::size=SomeQuantity;

I would like to initialize the array from 0...Size in steps of 1. E.g, if Size=10, myArray =[0,1,2,....,9]

Can the initialization of a static array be assigned to a function? Is there any C++ built in way of doing this?

Edit I could define inside the class:

static int initArray()
{
    for( int i = 0; i<sizeof(myArray)/sizeof(myArray[0]); i++)
    {
        myArray[i]=i;
    }
    return 0;
}

And afterwards initialize this as:

template <int Size>
int A<Size>::myArray[Size]={initArray()};

Kind regards

Write your own function, eg

int* MakeArray(const int size){
    int* res = new int[size];
    //stl generate transform or just a loop
    for (auto i=0;i<size;i++) res[i]=i;
    return res;
}
