Problem with reading from an array
As the title suggests im having trouble with writing from an array.
It seems as if even the i give the board[x][y] the correct values it's still reading from
the wrong point, i've looked through my code and cant find anything that's wrong, maybe you can help?
This is a simplified version of the code, with only the areas that are a problem.
Code:
#include <iostream>
#define WHITE_KING 6 // define all chess pieces for ease of use
#define WHITE_QUEEN 5
#define WHITE_TOWER 4
#define WHITE_RUNNER 3
#define WHITE_HORSE 2
#define WHITE_PEASANT 1
#define EMPTY 0
#define BLACK_PEASANT -1
#define BLACK_HORSE -2
#define BLACK_RUNNER -3
#define BLACK_TOWER -4
#define BLACK_QUEEN -5
#define BLACK_KING -6
using namespace std;
void initboard(void);
void drawboard(void);
int board[7][7];//global board variable
int main()
{
initboard();
drawboard();
system("PAUSE");//hold
}
void initboard(void)//initiate the board
{
int x,y;
for(y=0;y<=7;y++)//make sure all values are at zero
{
for(x=0;x<=7;x++)//loop through columns values, then go to the next row and redo
{
board[x][y]=EMPTY;
}
}
for(x=0;x<=7;x++)board[x][1]=WHITE_PEASANT;//white should be at the top rows
for(x=0;x<=7;x++)board[x][6]=BLACK_PEASANT;//black should be at the bottom rows
board[0][7]=BLACK_TOWER;//boring initialization stuff
board[1][7]=BLACK_HORSE;
board[2][7]=BLACK_RUNNER;
board[3][7]=BLACK_QUEEN;
board[4][7]=BLACK_KING;
board[5][7]=BLACK_RUNNER;
board[6][7]=BLACK_HORSE;
board[7][7]=BLACK_TOWER;
board[0][0]=WHITE_TOWER;
board[1][0]=WHITE_HORSE;
board[2][0]=WHITE_RUNNER;
board[3][0]=WHITE_QUEEN;
board[4][0]=WHITE_KING;
board[5][0]=WHITE_RUNNER;
board[6][0]=WHITE_HORSE;
board[7][0]=WHITE_TOWER;
}
void drawboard(void)
{
int x,y;
cout << " ";//proper alignment
for(x=0;x<=7;x++)cout << " " << x << " "; // the numbers above
cout << endl;// new row for layout
for(y=0;y<=7;y++)
{
cout << y;//numbers at the side of the grid
for(x=0;x<=7;x++)//loop through columns values, then go to the next row and redo
{
if(board[x][y]>=0)cout << " | " << board[x][y] << " | ";
else cout << " |" << board[x][y] << " | ";//one less space for negative value alignment
}
cout << endl;
}
}
If anyone has encountered this problem (or simply knows that i am doing something wrong) please do tell! I've been trying to fix this for a long while!
Thanks in advance.
