for all the users of borland, i need some help. im making a chess game the code is like this :
________________________________________________________________________________
#include <iostream>
using namespace std;
int main()
{
char c[8][8] = {};
c[0][3] = 'Q';
c[7][3] = 'q';
c[0][4] = 'K';
c[7][4] = 'k';
c[0][2] = 'N';
c[0][5] = 'N';
c[7][5] = 'n';
c[7][2] = 'n';
c[7][1] = 'b';
c[7][6] = 'b';
c[0][6] = 'B';
c[0][1] = 'B';
c[0][7] = 'R';
c[7][7] = 'r';
c[7][0] = 'r';
c[0][0] = 'R';
c[1][1] = 'P';
c[1][2] = 'P';
c[1][3] = 'P';
c[1][4] = 'P';
c[1][5] = 'P';
c[1][6] = 'P';
c[1][7] = 'P';
c[1][0] = 'P';
c[6][1] = 'p';
c[6][2] = 'p';
c[6][3] = 'p';
c[6][4] = 'p';
c[6][5] = 'p';
c[6][6] = 'p';
c[6][7] = 'p';
c[6][0] = 'p';
for(int i = 0; i<8; i++){
for(int j = 0; j<8; j++){
cout << c[j] << " ";
}
cout << endl;
________________________________________________________________________________
when i ompile that using borland it says somehting is wrong with the line that says:
char c[8][8] = {};
it says there is an expected expression in function main(). can someone tell me how to fix this?
Here's what you wrote:
int main() {
for(int i = 0; i<8; i++){
for(int j = 0; j<8; j++){
cout << c[j] << " ";
}
Number of opening brackets: 3
Number of closing brackets: 1
Also:
char c[8][8] = {};
is not a proper way to declare an array.
char c[8][8];
will do fine.
Do you know what an enum is? They're much less cryptic than using chars and will make your code more self-explanatory. Otherwise, good documentation would note your code: 'Q' = Queen, 'K' = King, 'N' = knight, etc. I'd expect 'k' to be knight, you see, but it's good that you didn't do that because it's a little easy to confuse K and k.

Possible use of enum for chess:
#include <iostream>enum player { black, white };enum piece { empty, pawn, bishop, knight, rook, queen, king };const char display[2][7] = {{'.', 'p', 'b', 'n', 'r', 'q', 'k'}, {'.', 'P', 'B', 'N', 'R', 'Q', 'K'}};struct field{ player pl : 1; piece pi : 3; bool is(player pla, piece pie) { return pl == pla && pi == pie; } friend std::ostream& operator<<(std::ostream& os, field f) { os << display[f.pl][f.pi]; return os; }};#define EMPTY {black, empty}#define EMPTYLINE {EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY, EMPTY},#define PAWNS(player) {{player, pawn}, {player, pawn}, {player, pawn}, {player, pawn}, {player, pawn}, {player, pawn}, {player, pawn}, {player, pawn}},#define LINE(player) {{player, rook}, {player, knight}, {player, bishop}, {player, queen}, {player, king}, {player, bishop}, {player, knight}, {player, rook}},int main(){ field board[8][8] = { LINE(black) PAWNS(black) EMPTYLINE EMPTYLINE EMPTYLINE EMPTYLINE PAWNS(white) LINE(white) }; for (int i = 0; i < 8; ++i) { for (int k = 0; k < 8; ++k) { std::cout << board[k] << ' '; } std::cout << std::endl; } if (board[0][0].pl == black) std::cout << "that's how you test for color\n"; if (board[0][0].pi == rook) std::cout << "that's how you test for piece\n"; if (board[0][0].is(black, rook)) std::cout << "that's how you test for colored piece\n";}You should possible make the board a class, too (if you know classes already).
Hm, the gamedev board doesn't seem to like the trailing backslash in macro definitions, it expands them itself :)
