1 7 This question will further change the rules of the game.
When a piece is promoted to a dame, the player who the new dame belongs to now
chooses one of the opponent’s pieces. This piece is removed from the board and the
dame is placed in the square the removed piece was in.
1 7 . 1 State the identifier of the data structure that now needs to be passed as a parameter
into the subroutine MoveDame.

What you need to do:
Task 1
Amend the subroutine MoveDame.
This subroutine is to:
• ask the player the piece ID of the opponent’s piece they want to remove
• check that the piece is an opponent’s piece and is on the board
• remove the opponent’s piece
• return the coordinates for the new dame.
Task 2
Amend the calls to MoveDame from within the subroutine MovePiece.
You will need to amend the parameter list of the subroutine heading of MovePiece
and the call to MovePiece from within the subroutine MakeMove.
Task 3
Test that the changes you have made work by conducting the following test:
• run the program
• enter Y
• load game3.txt
• move a2 to row 7, column 0
• take piece b1
Task 4
• move b5 to row 0, column 3
• take piece a6
