Suppose we have: 
   int x = 11;
   int y = 5;
   double z = 13.0;
   double w = 4.0;
Evaluate each of the following expressions:
  1. x/y
  2. x/w
  3. (x + z)/y
  4. (x * w)/y
  5. x % y
  6. x/(y-1)+z/(y-1) 
   a) 11/5 = 2
   b) 11/4.0 = 2.75
   c) 24.0/5 = 4.8
   d) 44.0/5 = 8.8
   e) 11 % 5 = 1
   f) 11/4 + 13.0/4 = 2 + 3.25 = 5.25
