Make a copy of piece.c and name it board.c.Modify your program so it reads in 16 pieces and places each one in a cell on a board from left-to-right, top-to-bottom. It should then print out the board. For simplicity we assume all piece input is entered in the same format as the previous exercises with exactly 1 space between them. Your program should behave as follows /board Enter pieces: R* Y^ B# Y* Y* Y* Y* B* Y^ R^ B^ R* R# R# R^ B* Y/* Y/* Y/ B/ /A R/ B/A R/* Try to use a top-down design approach when you do this. This means that as you modify your main function, try to design the prototypes of any functions you need to use n and use them in your main function. Once your main function is finished, go and implement these functions
