[C++知识库]有关c++继承总结

这是一篇关于继承的一个代码

#include<iostream>
#include<string>

using namespace std;

class mode
{
public:
	mode(){}
	mode(double high, double broad) :m_high(high), m_broad(broad)
	{
	}
	~mode(){}
protected:
	double m_high;
	double m_broad;
};
//三角形
class trigo :public mode
{
public:
	trigo(){}
	trigo(double high, double broad) :mode(m_high, m_broad)
	{
		proportion = (2 / 1)*(high*broad);
		cout <<"三角形面积"<< proportion << endl;
	}
	double proportion;
	~trigo(){}
};
//四边形
class quadrilateral :public mode
{
public:
	quadrilateral(){}
	quadrilateral(double high, double broad) :mode(m_high, m_broad)
	{
		proportion = high*broad;
		cout <<"四边形面积"<< proportion << endl;
	}
	double proportion;
	~quadrilateral(){}
};

int main()
{
	trigo price(20,10);
	quadrilateral price2(10, 20);
	system("pause");
}

补充：继承逻辑图以及取地址图
