c＋＋程序填空题

完成如下的程序，使得输出为：
1234
#include <iostream.h>
#include <math.h>
class A
{
private:
________(1)___________
protected:
________(2)__________
public:
A(int a, int b, int c)
{
X=a;
Y=b;
Z=c;
}
int GetX()
{
return X;
}
int GetY()
{
return Y;
}
int GetZ()
{
return Z;
}
};
class B _____(3)_______
{
private:
int K;
public:
B(int a, int b, int c, int d)_______(4)_________
{
K=d;
}
void Show()
{
cout << GetX() << GetY() << Z << K << endl;
}
};
void main()
{
B b(1,2,3,4);
b.Show();
}

//1234
#include <iostream.h>
#include <math.h>
class A
{
private:
//________(1)___________
int X,Y;
protected:
//________(2)__________
int Z;
public:
A(int a, int b, int c)
{
X=a;
Y=b;
Z=c;
}
int GetX()
{
return X;
}
int GetY()
{
return Y;
}
int GetZ()
{
return Z;
}
};
class B : public A//_____(3)_______
{
private:
int K;
public:
B(int a, int b, int c, int d): A(a,b,c)//_______(4)_________
{
K=d;
}
void Show()
{
cout << GetX() << GetY() << Z << K << endl;
}
};
void main()
{
B b(1,2,3,4);
b.Show();
}
//别忘了给分～

题有问题吧 A A为啥没调用

#include <iostream> using namespace std; class test { private:  int x,y; public:  test(){x=y=0; }  test(int a, int b)  {   x=a;y=b;  }  void print(){cout<<"x="<<x<<"y="<<y<<endl;} }; void main() { test t1(100,200),t2; test *p[]={(test*)&t1,(test*)&t2}; int i; for(i=0;i<=1;i++) p[i]->print(); }
