2. (10%) Determine whether the following code is correct or not.  If it is correct, predict its output.  If it is incorrect, point out the mistake(s).
   
   // Function prototype
   #include <iostream>
   using std::cout;
   using std::endl;
   
   void print_stars(int n);        // Function prototype
   
   int main()
   {
       int i;
       const int MAX = 5;
       for (i=1; i<=2*MAX-1; i++)
       {
           print_stars( i<=MAX ? i : 2*MAX-i);
       }
       return 0;
   }
   
   void print_stars(int n) // Function to print n stars
   {
        int j;
        for (j=0; j<n; j++)
            cout << '*';
        cout << endl;
        return;
   }
