title: In c++ what does Ptr<> a stands for?
body: <p>Im actually analysing some cod and i found this</p>
  
  <pre><code> Ptr&lt;UniformRandomVariable&gt; m_yMinVar;
  </code></pre>
  
  <p>i have some c experience but no c++, what i understand is that the line declare a pointer call m_yMinVar and it's "type" <code>&lt;UniformRandomVariable&gt;</code> where "UniformRandomVariable" must be a class in other cpp file but i really dnot know,</p>
  
  <p>i would like to know exactly what's Ptr because my text editor reconizes it as a variable type</p>
  
  <p>also "&lt;>" i'm not sure thats that </p>
  
  <p>and finaly if someone can share me a link where i can see operators and diferent kinds of declaring variables and coding types like " i++ = i+=  i=i+1"</p>
  
  <p>doodbye everybody and thank u all</p>
