c++ ifstream printing last item in file twice

Question

I want to read the data from the file afile.dat and then print the data to the screen. The content of the file is as follows:

Max
20

In order to print the two items to the screen I wrote the following C++ program:

#include <fstream>
#include <iostream>
using namespace std;


int main () 
{

   char data[100];

   ifstream infile; 
   infile.open("afile.dat"); 

   cout << "Reading from the file" << endl; 

   while(infile){   
        infile >> data;
         cout << data << endl;  
   }

   infile.close();

   return 0;
}

The output of this program is:

Max
20
20

Why is "20" printed twice?
