What's wrong with this constructor?
<pre><code>class Ball
{
    public:
    int i,j,iplus,jplus;
    Ball(int i , int j , int iplus , int jplus)
    {   iplus=1; 
        jplus=1; 
        i=400;
        j=300;
    }
};
int main()
{
        Ball toop(Ball);
}
</code></pre>

<p>I get the following error:</p>

<blockquote>
  <p>request for member ‘jplus’ in ‘toop’, which is of non-class type ‘Ball(Ball)’</p>
</blockquote>
