Program 16 Define a class Mirror_matrix to input and print the mirror of a user-defined matrix. The data
members and member methods are defined as follows:
Data Members
int a[][] : to store the array
int n : to store the size of the matrix
Member Methods
void input() : to input the array
void mirror() : to find the mirror of the matrix and print it
Write the main method to call the methods and print the mirror of the matrix.
