Write a $C++$ program utilizing constructors and destructors to manipulate an

array of non$-$negative integers, 'arr', by cyclically shifting its elements to the

right by $k$ positions. For instance, given an input array arr $=[1,2,3,4,5,6,7]$

and a shift value $k=3,$ the program should output the transformed array

$5,6,7,1,2,3,4.$ If shift value $k=1,$ then the output should be $7,1,2,3,4,5,6.$

Illustrate the working of the algorithm and provide comments with

explanation for the code.

Note: The input array should be passed to the constructor of the "ShiftArray"

class from the main function.
