Write a C$++$ program to do operation for $2$D array.

$2\mathrm{.}1-(10)$ The program prompts the user to enter a two$-$dimensional array $(4$x$4)$ of int numbers.

$2\mathrm{.}2-(10)$ The program prints that array and calls isIdentity$()$ function to check whether the entered matrix is an

identity array or not.

Identity array: in which all the elements on the main diagonal are equal to $1$ and all other elements are equal to $0.$

$2\mathrm{.}3-(10)$ The program then calls spiralOrder$()$ function to traverse the matrix in a clockwise spiral pattern and

outputs the elements in the
