Differentiating a pointer from an array.

Is there any way to differentiate a pointer from an array.

void Fun(int* p)
{
    // For these values to be proper p should be array of two
    // But how to check if p is an array or is a pointer ?
    int i = p[0];
    int j = p[1];
}

void main()
{
    int a[2] = {1, 2};
    Fun(a);

    int* b = new int;
    *b = 1;
    Fun(b);
}

There are always better alternatives to do this in a better way.

But I want to know if we can differentiate?
