C++二维数组作函数参数

1、函数声明

//map_countCol为const常量
//m为二维数组名

void DrawMap(int s, QString m[][map_countCol]);

 2、函数定义

void Game::DrawMap(int s,QString m[][map_countCol])
{
	qDebug() << "Game::DrawMap";
	QPainter p(this);
	for (int i = 0;i < map_countRow;i++)
	{
		for (int j = 0;j < map_countCol;j++)
		{
			if (m[i][j] == "1")
			{
				p.drawPixmap(j * s, i * s, s, s, QPixmap(MAN));
			}
			if (m[i][j] == "2")
			{
				p.drawPixmap(j * s, i * s, s, s, QPixmap(ZA));
			}
			if (m[i][j] == "3")
			{
				p.drawPixmap(j * s, i * s, s, s, QPixmap(CAKE));
			}
			if (m[i][j] == "4")
			{
				p.drawPixmap(j * s, i * s, s, s, QPixmap(BOX_1));
			}
		}
	}
}

3、函数调用

DrawMap(step, &_map[0]);

//可在函数体内修改_map的数值
//int step;
