Simple tree

I'm trying to build a very simple tree
with my class A this way:


class  A
{
 public:
 Int_t a; 
 Int_t b; 
};



A *CC;


TROOT simple("simple","trees");
 
 main()
 {

   Int_t split = 0;
   Int_t bsize = 32000;


// Create a ROOT Tree

TTree *tree = new TTree("T","An example of ROOT tree");
tree->Branch("aa","A",&CC,bsize,split);


   return 0;
 }
                                                                      

and I'm getting the message 

Error in <TTree::BranchObject>: Cannot find class:A


What am I doing wrong?
