C++继承中属性对象重名和多父类继承

#include

using namespace std;
class fa {
public:
	int m = 1000;
	void shuchu() {
		cout << "fa类的shuchu对象"<
		cout << "fa类的shuchu对象的int重载"<

	cout << "同名成员函数处理方法" << endl;
	cout << "son下的函数：" << endl;
	s.shuchu();
	cout << "nfa下的函数：" << endl;
	s.fa::shuchu();//调用父类需要作用域
	//s.shuchu(100);//报错
	s.fa::shuchu(100);
}
