/* Note
   (1) Since Integer1,Integer2 and Integer3 are integer numbers, the result
       of any calculation on these numbers will be integer also. Let's say
       Integer1 is 3, Integer2 is 4 and Integer3 is 6, then the sum of these
       3 numbers is 3+4+6 = 13 and average is 4 (by default). If we need the
       result in floating-point representation, then we must add the key word
       "float" before calcauation :

       Average1 = Sum / 3;          = 4       (int)
       Average2 = float (Sum) / 3;  = 4.33333 (float)

       BUT NOT  :  Average2 = float(Sum / 3);
