如下程序执行后的输出结果是 【14】 。
#include ＜iostream＞
using namespace std;
class Base
{
public:
Base(int x,int y)
{
a=x;
b=y;
}
void Show()
{
cout＜＜"Base: "＜＜a＜＜ ’,’ ＜＜b＜＜" ";
}
private:
int a,b;
};
class Derived : public Base
{
public:
Derived(int x, int y, int z) : Base(x,y),c(z) { }
void Show()
{
cout＜＜"Derived:"＜＜c＜＜end1;
}
private:
int c;
};
int main()
{
Base b(100,100),*pb;
Derived d(10,20,30);
pb=&b;
pb-＞Show();
pb=&d;
pb-＞Show();
return 0;
}
【参考答案】
Base：A00,A00 Base：A0,B0
