In the following program input should be of the form: U-for unoccupied,B- occupied by black,W-occupied by white. The program should ask for user configuration once it initializes the board and then it prints the board using the user configuration. Then it prints the available moves for 'W' & 'B' accordingly. The last step is to ask for a move from the used and if it matches with the available moves printed before then it prints a message of the move is valid, then it prints the board for the last time using the valid move. I am getting some weird output here after it prints the configured board. please help here, thank you. here is an example input and expected output:
#include <stdio.h>
#include <stdlib.h>
#include <stdbool.h>
