Expected output of :

Enter the number of rows of arrys:2
Enter the number of colums of arrys:3

Enter values of first 2d arrays:
Enter values of array element for 0 row and 0 coulm:1
Enter values of array element for 0 row and 1 coulm:2
Enter values of array element for 0 row and 2 coulm:3
Enter values of array element for 1 row and 0 coulm:3
Enter values of array element for 1 row and 1 coulm:2
Enter values of array element for 1 row and 2 coulm:1

Enter values for 2nd arry element
Enter values of array element for 0 row and 0 coulm:1
Enter values of array element for 0 row and 1 coulm:2
Enter values of array element for 0 row and 2 coulm:3
Enter values of array element for 1 row and 0 coulm:3
Enter values of array element for 1 row and 1 coulm:2
Enter values of array element for 1 row and 2 coulm:1

First aaray elements are
  1  2  3
  3  2  1
Second aaray elements are
  1  2  3
  3  2  1



sum of arry element
  2  4  6
