MATRIX SYMMETRIC

Write a program to declare a square matrix A[][] of order MxM where ‘M’ is the number of rows and the number of columns, such that M must be greater than 2 and less than 10. Accept the value of M as user input. Display an appropriate message for an invalid input. Allow the user to input integers into this matrix. Perform the following tasks:
a) Display the original matrix.
b) Check if the given matrix is symmetric or not. A square matrix is said to be symmetric, if the element in the ith row and jth column is equal to the element of the jth row and ith column.
c) Find the sum of the elements of left diagonal and the sum of the elements of right diagonal of the matrix and display them.
Test your program for the following data and some random data:
Example 1
INPUT: M= 3
1 2 3
2 4 5
3 5 6
OUTPUT:
ORIGINAL MATRIX
1 2 3
2 4 5
3 5 6
THE GIVEN MATRIX IS SYMMETRIC
The sum of the left diagonal = 11 The sum of the right diagonal = 10
Example 2
INPUT: M= 4
7 8 9 2
4 5 6 3
8 5 3 1
7 6 4 2
OUTPUT:
ORIGINAL MATRIX
7 8 9 2
4 5 6 3
8 5 3 1
7 6 4 2
THE GIVEN MATRIX IS NOT SYMMETRIC
The sum of the left diagonal = 17 The sum of the right diagonal = 20
Example 3
INPUT: M= 12
OUTPUT:
THE MATRIX SIZE IS OUT OF RANGE
