Chess Console Game in C++

This article is about a simple chess game in C++ that runs in a console. All input is taken from the keyboard, and for that, it uses the Coordinate Notation.

void printBoard(Game& game)
{
   cout << "   A     B     C     D     E     F     G     H\n\n";

   for (int iLine = 7; iLine >= 0; iLine--)
   {
      if ( iLine%2 == 0)
      {
         // Line starting with BLACK
         printLine(iLine, BLACK_SQUARE, WHITE_SQUARE, game);
      }

      else
      {
         // Line starting with WHITE
         printLine(iLine, WHITE_SQUARE, BLACK_SQUARE, game);
      }
   }
} 

void printLine(int iLine, int iColor1, int iColor2, Game& game)
{
   // Define the CELL variable here. 
   // It represents how many horizontal characters will form one squarite
   // The number of vertical characters will be CELL/2
   // You can change it to alter the size of the board 
   // (an odd number will make the squares look rectangular)
   int CELL = 6;

   // Since the width of the characters BLACK and WHITE is half of the height, 
   // we need to use two characters in a row.
   // So if we have CELL characters, we must have CELL/2 sublines
   for (int subLine = 0; subLine < CELL/2; subLine++)
   {
      // A sub-line is consisted of 8 cells, but we can group it
      // in 4 iPairs of black&white
      for (int iPair = 0; iPair < 4; iPair++)
      {
         // First cell of the pair
         for (int subColumn = 0; subColumn < CELL; subColumn++)
         {
            // The piece should be in the "middle" of the cell
            // For 3 sub-lines, in sub-line 1
            // For 6 sub-columns, sub-column 3
            if ( subLine == 1 && subColumn == 3)
            {
               cout << char(game.getPieceAtPosition(iLine, iPair*2) != 0x20 ? 
                             game.getPieceAtPosition(iLine, iPair*2) : iColor1);
            }
            else
            {
               cout << char(iColor1);
            }
         }

         // Second cell of the pair
         for (int subColumn = 0; subColumn < CELL; subColumn++)
         {
            // The piece should be in the "middle" of the cell
            // For 3 sub-lines, in sub-line 1
            // For 6 sub-columns, sub-column 3
            if ( subLine == 1 && subColumn == 3)
            {
               cout << char(game.getPieceAtPosition(iLine,iPair*2+1) != 0x20 ? 
                              game.getPieceAtPosition(iLine,iPair*2+1) : iColor2);
            }
            else
            {
               cout << char(iColor2);
            }
         }
      }
   }
}

This game runs in a console, i.e., that means no GUI is available to the user. All the input is taken from the keyboard. First, we have to decide how big we want the squares do be. Speaking about the height, should one square on the board be as big as one single character? Or maybe two or three? More Information Visit UTS Backlinks
