Pick one. My preference is Foo.

#include <iostream>
#include <vector>

extern const int dim; //dimension of the array

const int dim = 10;

class Foo
{
public:
    Foo( const int Size )
    {
        x.resize( Size );
    }
    std::vector<double> x;
};

class Foo2
{
public:
    Foo2()
    {
        x.resize( dim );
    }
    std::vector<double> x;
};

class Bar
{
public:
    Bar( const int Size ) { x = new double[ Size ]; }
    ~Bar() { delete[] x; }
    double* x;
};

class Bar2
{
public:
    Bar2() { x = new double[ dim ]; }
    ~Bar2() { delete[] x; }
    double* x;
};

int main()
{
    Foo foo( dim );
    Foo2 foo2;
    Bar bar( dim );
    Bar2 bar2;

    return 0;
}
