   3 Solution of exercise 2.19:
   4 (Arithmetic, Largest Value and Smallest Value) Write a program that inputs
   5 three different integers from the keyboard, then prints the sum, the average,
   6 the product, the smallest and the largest of these numbers. Use only the
   7 single-selection form of the if statement you learned in this chapter. The
   8 screen dialogue should appear as follows:
   9
  10     Input three different integers: 13 27 14
  11     Sum is 54
  12     Average is 18
  13     Product is 4914
  14     Smallest is 13
  15     Largest is 27
