OOP, assigment operator does not work
<p>This is from my code:</p>

<pre><code>struct R3
{
       float x;
       float y;
       float z;

       R3(float, float, float);
       R3();
};

R3::R3(float a, float b, float c)
{
        x = a;
        y = b;
        z = c;
}

R3::R3()
{
        x = 0;
        y = 0;
        z = 0;
}

struct Bodies
{
       int Mass;
       float Dist[100];
       R3 Place(float, float, float);
       R3 Speed(float, float, float);
       R3 Acc(float, float, float);

       Bodies(int, R3, R3, R3);
};

Bodies::Bodies(int M, R3 XYZ, R3 V, R3 A)
{
       Mass = M;
       Place = XYZ;
       Speed.x = V.x;
       Speed.y = V.y;
       Speed.z = V.z;
       Acc.x = A.x;
       Acc.y = A.y;
       Acc.z = A.z;
}
</code></pre>

<p>My problem is, that for Place = XYZ;, it's showing the error "invalid use of member (did you forget the '&amp;'?)"
and for Speed.x = V.x; "insufficient contextual information to determine type".</p>

<p>I'm quite new to OOP, and I don't see where the problem might be.</p>

<p>Could you please tell me why doesn't it work?</p>

<p>Thanks.</p>
