源程序:

#include <iostream>

using namespace std;

class BaseClass

{

public:

  int v1, v2;

  BaseClass()

  {

    v1 = 1;

    v2 = 1;

  }

  int temp1() {}

};

class DerivedClass :public BaseClass

{

  int v1;

  int temp1() {}

public:

  DerivedClass()

  {

    v1 = 10;

  }

  void printv()

  {

    cout << "v1=" << v1 << endl;

    cout << "Base.v1=" << BaseClass::v1 << endl;

  }

};

int main()

{

  BaseClass bc;

  DerivedClass dc;

  dc.printv();

  system("pause");

  return 0;

}
