Program 17 Define a class Spiral_Matrix to input and print the spiral of a user-defined matrix (2-D array).
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 array
Member Methods
void input() : to input the size of the array
void spiral() : to find the spiral matrix and print it
Write the main method to call the methods and print the spiral of the matrix.
