第一种方法:#include #include using namespace std;class father{protected:string name;int tall;public:father(string a, int i);father(){cout << "构造基类" << endl;}void print(){cout << name << "身高为: " << tall <<

函数的隐藏和覆盖在C++中区别是非常之大#include using namespace std;class a{public: void hello() { cout << "基类a的hello函数" << endl; } void hello(int i) { cout << "a.hello(i): " << i << endl; cout << "基类a的
