八皇后C++实现

#include <iostream>
using namespace  std;
#define squares  8
class ChessBoard
{
public:
ChessBoard();
ChessBoard(int);
void findSolutions();
void printBoard();
private:

void initalizeBoard();
};
ChessBoard::ChessBoard():avaliable(true),norm(squares-1)
{
initalizeBoard();
}
ChessBoard::ChessBoard(int n):avaliable(true),norm(squares-1)
{
initalizeBoard();
}
void  ChessBoard::initalizeBoard()
{
register int i;//寄存器，放置在CPU中，因为会常用到这个变量
colum=new bool[squares];
