Answer 1

Program F90

   integer i, j, k, s /0/, x/2/, y/6/, a(7, 7)

   do k = 1, 4

       do i = x - 1, y + 1

           s = s + 1

           a(x - 1, i) = s

       end do

       i = y + 1

       do j = x, y + 1

           s = s + 1

           a(j, i) = s

       end do

       do i = y, x - 1, -1

           s = s + 1

           a(y + 1, i) = s

       end do

       i = x - 1

       do j = y, x, -1

           s = s + 1

           a(j, i) = s

       end do

       x = x + 1

       y = y - 1

   end do

   Print *, 'massive 15 = '

   Write(*, '(7i5)') ((a(i, j), j=1, 7), i=1, 7)

End Program
