C语言实现面向接口编程

面向接口编程

• 实现公司中编程方式
• 甲方和乙方商定好接口，分别实现自己的功能
• 最后对接成功，实现游戏功能

代码示例：

面向接口编程.c

//游戏战斗
typedef int(*FIGHT_GAME)(void*gameHandle, int gameLevel);
//查看玩家信息
typedef void(*PRINT_GAME)(void *gameHandle);
//离开游戏
typedef void(*CLOSE_GAME)(void *gameHandle);
void playGame(INIT_GAME init, FIGHT_GAME fight, PRINT_GAME printGame, CLOSE_GAME  closeGame)
