一个简单的数值计算程序所使用的数据是一些实数或整数

#include <iostream.h>

class Parent
{
protected:
	char version;
public:
	Parent(){version = 'A';}					   		//构造函数
};

class Derived1: public Parent
{
private:
	int info;
public:
	Derived1(int number)				   //构造函数
		{info = number; }
	void Print()
		{cout << "Version and info of Derived1 is: "
			 << version << info << endl;}
	void Test()
		{cout << "继承方式测试" << endl;}
};

class Derived2: private Parent
{
private:
	int info;
public:
	Derived2(int number)				   //构造函数
		{info = number; }
	void Print()
		{cout << "Version and info of Derived2 is: "
			 << version << info << endl;}
};

void main(void)
{
	Parent base;
	Derived1 d1(10);
	Derived2 d2(20);

	d1.Print();
	d2.Print();
	d1.Test();		//合法
//	d2.Test();		//非法
}
