有以下程序:
#include ＜iostream＞
using namespace std;
class Base
{
private:
int a,b;
public:
Base(int x, int y)
{
a=x;
b=y;
}
void Show()
{
cout＜＜a＜＜ ’,’ ＜＜b＜＜end1;
}
};
class Derived : public Base
{
private:
int c;
public:
Derived(int x, int y, int z) : Base(x,y),c(z) {}
void Show()
{
cout＜＜c＜＜end1;
}
};
int main()
{
Base b(50,50),*pb;
Derived d(10,20,30);
pb=&d;
pb-＞Show();
return 0;
}
运行后的打印结果为 【14】
