c++坦克大战代码实现

C++坦克大战的代码实现比较复杂，需要使用图形库来实现游戏界面的设计。下面是一个简单的C++坦克大战代码实现示例，仅供参考：

#include <conio.h>
#include <stdlib.h>
#include <time.h>

#define BATTLE_WIDTH 640
#define BATTLE_HEIGHT 480
#define CELL_SIZE 16
#define TANK_SIZE 32
#define MAX_BULLETS 10
#define MAX_ENEMIES 5

这个代码实现了基本的游戏功能，包括坦克的移动、炮弹的发射、敌人的生成、敌人的移动和炮弹的碰撞检测等。但是代码实现还不够完善，需要根据实际情况进行调整和完善。
