====== are references safer than pointers? ======

<code c++>
struct A
{
    A(int& a)
        : m_a(a)
    {}

    void print()
    {
        std::cout << m_a << std::endl;
    }

    int& m_a;
};

int main(int argc, char* argv[])
{
    int* b = new int();
    *b = 1234567890;

    A a(*b);
    a.print();

    *b = 43210;
    a.print();

    delete b;
    a.print();

    return 0;
}
</code>

prints the following:

<code>
1234567890
43210
-572662307
