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;
}
运行结果：
