RPG角色生成器（C++）

角色生成器需要记录玩家输入的名字,选择的性别,种族,职业,并且根据不同职业所随机生产的属性也不相同。

1.设计思路

首先建一个基类Base用来保存和实现,保存玩家输入的姓名和性别的选择,同时需要声明两个友缘类Output，File可以访问该类中的数据。

在基类Base基础上建一个派生类Race,用来记录玩家选择的种族,和职业,同时规定什么种族可以选择什么职业，人类可以选择全部职业；精灵不能选择狂战士，圣骑士；兽人不能选择圣骑士，刺客；矮人不能选择刺客，猎手；元素只能选择祭司，同时需要声明两个友缘类Output，File可以访问该类中的数据。

在派送类Race基础上派生一个Attribute类用来记录角色随机生产的属性，首选规定各个职业每个属性的最小值，在这个最小值的基础上，随机生成差距在3左右的属性，再根据随机生产的属性计算出该角色的血量值，法力值，同时需要声明两个友缘类Output，File可以访问该类中的数据。

建立一个Output类可以访问Base，Race，Attribute三个类中的数据，输出三个类中记录的数据。

建立一个File类可以访问Base，Race，Attribute三个类中的数据，并且将三个类中的数据进行文本输出保存。

3.面对对象原则应用

      该程序中用到了，开闭原则，单一职责。
