title: Assigning general classes as null in C++
body: <p>I am having kind of a trouble adapting a program from C# to C++. It's very commom given a class to assign it the null value. But C++ is not accepting the equivalent form 'nullptr'</p>
  <pre><code>class Point{
       public:
           int x,y;
  }
  //...
  Point p = nullptr;
  </code></pre>
  <p>There is some way of solving it?</p>
