Question

Use this class the create a program that moves a single checker piece across a board and then have it return to its starting square. Your program should output the game-board after every move it makes to show its progress.

Need help finishing it.

#include <iostream>
using namespace std;

class checkerPiece
{
private:
   int xPosition = 0;//from 0 to 7
   int yPosition = 0;//from 0 to 7  

   bool king = 0;//0 is not king, 1 is king

public:
   char color;//b for black and r for red

   void upRight();
   void upLeft();
   void downRight();
   void downLeft();
   int xPositionReturn();
   int yPositionReturn();

};

void checkerPiece::upRight()
{
   if (color == 'b')
   {
       if ((xPosition + 1 <= 7) && (yPosition + 1 <= 7))
       {
           xPosition++;
           yPosition++;
       }
   }
   else if (color == 'r')
   {
       if ((king == 1) && (xPosition + 1 <= 7) && (yPosition + 1 <= 7))
       {
           xPosition++;
           yPosition++;
       }
   }

   {
       king = 1;
   }

}

       }
   }

   {
       king = 1;
   }

}

   display(testPiece);
   testPiece.upRight();//starting point
   //how to make it across the board (to the top) and then have it return to its starting point

Explanation / Answer

void doClickSquare(int row, int col) { // This is called by mousePressed() when a player clicks // on the square in the specified row and col. It has already // been checked that a game is, in fact, in progress. /* Check that the user clicked an empty square. If not, show an error message and exit. */ if ( board[row][col] != EMPTY ) { if (currentPlayer == BLACK) message.setText("BLACK: Please click an empty square."); else message.setText("WHITE: Please click an empty square."); return; } /* Make the move. Check if the board is full or if the move is a winning move. If so, the game ends. If not, then it's the other user's turn. */ board[row][col] = currentPlayer; // Make the move. Graphics g = getGraphics(); drawPiece(g, currentPlayer, row, col); // Draw the new piece. g.dispose(); if (winner(row,col)) { // First, check for a winner. if (currentPlayer == WHITE) gameOver("WHITE wins the game!"); else gameOver("BLACK wins the game!"); return; } boolean emptySpace = false; // Check if the board is full. for (int i = 0; i < 13; i++) for (int j = 0; j < 13; j++) if (board[i][j] == EMPTY) emptySpace = true; // The board contains an empty space. if (emptySpace == false) { gameOver("The game ends in a draw."); return; } /* Continue the game. It's the other player's turn. */ if (currentPlayer == BLACK) { currentPlayer = WHITE; message.setText("WHITE: Make your move."); } else { currentPlayer = BLACK; message.setText("BLACK: Make your move."); } } // end doClickSquare()
