Hi! I'm making a chess program, that need to move pieces on the chess board, get an input,check if the move is valid and print the output. The compiler finds some errors that i don't understand...I need some help with the pieces functions. Plz help me fix them!!!
my attempts :
//Chess project//
#include <cstdlib>
#include <iostream>
using namespace std;
#include<stdio.h>
#include<string.h>
#include<stdlib.h>
// all figures are represented as a constant integers//
//constants
// all columns are presented as an integers
#
int board[8][8];//chess board is presented as a 2D array of int
#define empty 0
#define pawn 1
#define rook 2
#define knight 3
#define bishop 4
#define queen 5
#define king 6
//functions declaration
