四、编程题(第1题20分，第二题12分，共32分) 4
1. 创建一个顶层基类Artist, 其中有name和age两个属性以及show(兩数用来显示
各项属性值;按着创建两个派生类Actor 和Singer,并增加额外的fansAmount和income
属性，并且也具有show0函数:最后使用Actor和Singer类派生出一个底层派生类Star,
并额外增加一个属性forbesRank, 并且包含show0函数;请使用虚基类来避免多级及
Anc
多重继承后出现的二义性，在main函数中分别创建Artist类对象、Aclor类对象、Singer
类对象以及一个Star类对象，并分别使川show0函数显示其各项数据。4
