Depending on the programming language they are: - separated by a comma: first, second; This is what we will use in the tutorial.Here is one example: numbers3, 4 is a 2D array, named numbers.
It is an interesting case and it is often used in calculations. It also has some additional characteristics that we will look into: main diagonal, secondary diagonal, elements above the diagonal and elements under the diagonal. All elements in a square matrix that have equal indices (i j) form the main diagonal (see the table below note that in this example inside the table are written the indices, not the values). If we have the coordinates of two pieces we can find if they attack each other. For such tasks the input data are integer variables, containing the position of those pieces. The coordinates are in the variables Rr, Rc, Br, Bc(RookRow, RookColumn, BishopRow, BishopColumn). Chess rules state that the rook can attack by straight line either horizontal or vertical. If it attacks the bishop, then they are on the same row or column. Lets make one example to see how it looks like on the chess board. Given are the coordinates of a white queen and a black queen. Helper: the queen can move and attack both by straight line(like a rook) and by diagonal(like a bishop).
