```
程序中定义了多个类,每个类都实现了一个父类的接口。其中:
- 类C公共继承了A和B,实现了父类接口,并重写了父类的虚函数。
- 类D保护继承了A,实现了父类接口,并重写了父类的虚函数。
- 类E私有继承了A,实现了父类接口,并重写了父类的虚函数。
- 类F多级继承了C和D,实现了父类接口,并重写了父类的虚函数。
- 类G虚继承了A,实现了父类接口,并重写了父类的虚函数。
- 类H虚继承了A和B,实现了父类接口,并重写了父类的虚函数。
- 类I组合了A,实现了父类接口,并调用了A的虚函数。
- 类J组合了A和B,实现了父类接口,并调用了A和B的虚函数。
- 类K继承了C和G,实现了父类接口,并重写了父类的虚函数。
- 类L继承了H和I,实现了父类接口,并重写了父类的虚函数。
- 类M继承了F和J,实现了父类接口,并重写了父类的虚函数。
在main函数中,分别创建每个类的对象,并调用其接口函数。输出结果可以看到,每个类都按照预期实现了父类的接口,并调用了正确的虚函数。
希望这个示例程序对你有所帮助,如果还有什么问题,请随时提出。
