 *Description:
 26 (Checker board)
Write a program that randomly fills in 0s and 1s into an 8 x 8 checker board,
prints the board, and finds the rows, columns, or diagonals with all 0s or 1s.
Use a two-dimensional array to represent a checker board. Here is a sample run of the program:

10101000
10100001
11100011
10100001
11100111
10000001
10100111
00100001
All 0's on subdiagonal
