/* Display of above program

(1) Display all array elements:
   43   24   71   98   19   53   76   62   39   16   51   67   47   75   23   82
   39   76   25   61

(2) Search and display largest integer: 98

(3) Search and display all odd integers:
   43   71   19   53   39   51   67   47   75   23   39   25   61

(4) Display all integers within user designated range
Please input the lower end of the range: 20
Please input the upper end of the range: 50
The integers within that range are:
