Please write a program (in C) that prints out the pattern of an 8x8 chessboard. Please use a 2D pointer of dynamic array of chars, you may use a nested for-loop to assign patterns. Suggested imitating patterns are [ ] for white check, and [X] for black one. If you could also mark down the 1-8, A-H coordinates for the board, it will make the chessboard more ready for use. [Don't forget to free() your dynamic arrays]
