SPIRAL PRINT OF 2-D ARRAY USING C++

  . Traverse the first row and print the elements of the first row from left to right,

    then increment in the first row.  

  . Now, traverse the last column and print the elements from top to bottom,

    and then decrement in the last column.

     after that decrement in the last row.

  . traverse the first column and print the elements from bottom to top,

       then increment in first column and so on.
