/*PROGRAM DESCRIPTION
The following is a menu-driven program. Within the program the user can choose:
-Help
-Smallest
-Largest
-Quit
if the user selects smallest then he/she will be prompted to enter the size of the array
they want to examine. Following that, the user will be prompted to input the values for
the actual elements within the array. A function findSmallest will be called which will
read and compute the users input and find the smallest value and the frequency of occurence.
The same procedure will be followed for Largest, except that the largest number will be found.
