C++问题面相对象编程敲击键盘产生猫

Question

编写程序，实现每按一次任意键时就将一只猫放在一个围栏里，这个围栏可以容纳7只猫。每只猫都是一个类Cat的实例化对象。在实例化每只猫时，都会随机地赋予一种毛色（如：Black、Gray或Brown），还将被随机地赋予一种眼睛颜色（如：Green、Blue或Brown）以及毛长（short、long）。对于这三种属性，程序提供set和get方法。

将猫放在围栏中，某些组合会发生争斗。例如，如果灰猫的数量超过棕色猫的数量，灰猫就会与棕色猫打架。如果在围栏里有一只黑毛、棕色眼睛的猫，同时还至少有一只黑色绿眼睛猫和至少一只黑色蓝眼睛猫，也会发生争斗。

分别输出7只猫的特征， 并判断猫是否会打架。

不知道这个程序运行后有没有达到你的作业要求，你拿去运行试试结果，还有疑问请私密我。
