博文背景：
还记大二上学期的时候看的这个C++&RPG游戏（博主大一下学期自学的php,涵盖oop内容）,一个外校的同学他们大一学的C++,大二初期C++实训要求做一个程序填空，就是这个 RPG 对战游戏，有几处空需要填上，问我可以不，我就信誓旦旦的说OK,最后“万般无奈多方考究”才给将程序补充完整。最近在做毕业设计，用到C++&QT oop部分，重新温习了下C++ oop,就想起来大二的时候还“捣鼓”过这么个游戏，现重新看了下，进行整理总结，写下该博文。
--------------------华丽的分割线，开始正题-----------------
本RPG游戏介绍：
用户创建一个玩家，与AI进行PK,PK中，可以普通攻击（随机暴击、躲闪）、技能攻击、加血、加蓝。本游戏中指定了5个对手，任务失败或者打败所有对手游戏结束。
代码架构：
mian.cpp:控制游戏流程.
container.h container.cpp:物品类.
player.h player.cpp:角色类.
swordsman.h swordsman.cpp:剑士角色.
archer.h archer.cpp:弓箭手角色.
mage.h mage.cpp:魔法师角色.
每个角色都需要物品，每个角色都继承与角色类。
全部代码如下：
