Question

我正在制作一个Tic-tac-toe游戏，我有一个包含9个tile类实例的棋盘类，并对它们做了一些事情。起初我使用C数组来创建那些实例Tile board[MAX_TILES]，一切都可以正常使用它们。但是我想使用向量，因为它们更安全，所以我尝试使用向量std::vector<Tile> board(MAX_TILES);，但我在.cpp文件中遇到了一堆错误，在我的.h文件中出现了2个错误。

我不习惯向量，因为我被大学教授教过使用C风格阵列。我做错了什么？

这是我的Board.h和错误，如果你需要.cpp，我将提供：

#ifndef BOARD_H
#define BOARD_H

#include <SFML\Window.hpp>
#include <vector>

#include "tile.h"

#define MAX_TILES 9

enum Position
{
    TOP_LEFT        = 0,
    TOP_MIDDLE      = 1,
    TOP_RIGHT       = 2,
    MIDDLE_LEFT     = 3,
    MIDDLE_MIDDLE   = 4,
    MIDDLE_RIGHT    = 5,
    BOTTOM_LEFT     = 6,
    BOTTOM_MIDDLE   = 7,
    BOTTOM_RIGHT    = 8
};

class Board
{
private:
    std::vector<Tile> board(MAX_TILES);
    //Tile board[MAX_TILES];
    void positionTiles();
public:
    //Constructors
    Board();
    Board( TileState tileState );
    //Methods
    void clearBoard();
    void drawBoard(sf::RenderWindow& window);

};

#endif

错误1和2来自.h，其他来自.cpp：

Answer 1

你不能在C ++ 03中这样做。

std::vector<Tile> board(MAX_TILES);

你应该在电影中使用它。

Board():board(MAX_TILES)
{
}

Answer 2

只需快速查看，您需要在Board的构造函数中初始化向量，而不是在类定义中。

Answer 3

C ++ 03不支持初始化列表。如果这是C ++ 11，那么你必须使用{}。

数组工作，而矢量没有。我究竟做错了什么？
