CMIS 140 Lab exercise Modify the checkers.cpp program (available online, don't type it) to count the number of red and black pieces on the board. Modify the checkers.cpp program so that it displays a border and interior lines. Add code that loops asking player(s) to enter the coordinates (row and column) of a piece to move and the coordinates to move it to. Display the board after each move. Modify it so that it initializes the board as a real checkers game. r r r r r r r r r r r r b b b b b b b b b b b b Hint: on rows 0 and 2, it's the odd columns that have a piece; on row 1 it't the even columns.
