  Try like this:

 Better solution (more O-oriented):

  TList HistList;
  for(i=0, i<100, ++i)
  {
    HistList.Add( new TH1F( STUFF DEPENDIING ON i) );
    HistList.Add( new TH2F(MORE STUFF DEPENDING on i) );

    .
    .
    .
      // Find your histogram

       TH1F *want1DimToWorkWith =  (TH1F *)HistList.FindObject("histogram name")
       TH2F *want2DimToWorkWith =  (TH2F *)HistList.FindObject("another histogram name")

      //Store the numbers of counts in arrays
      //Now it's time to get rid of them !!!
 
  }
  Histlist.Delete();

  Hope this helps
