//继承的语法：class 子类；继承方式：父类
//继承方式有三种
//1、公共继承
class Base1
{
public:
	int m_A;
protected:
	int m_B;
private:
	int m_C;
};

class Son1 :public Base1
{
public:
	void func()
	{
		m_A = 10; //父类中的公共权限 到子类中依然是公共权限
		m_B = 10; //父类中的保护权限 到子类中依然是保护权限
		//m_C = 10;//父类中的私有权限 到子类中访问不到
	}

};
//2、保护继承
class Base2
{
public:
	int m_A;
protected:
	int m_B;
private:
	int m_C;
};

class Son2 :protected Base2
{
public:
	void func()
	{
		m_A = 100; //父类中的公共权限 到子类中依然是保护权限
		m_B = 100; //父类中的保护权限 到子类中依然是保护权限
		//m_C = 10;//父类中的私有权限 到子类中访问不到
	}

};
//3、私有继承
class Base3
{
public:
	int m_A;
protected:
	int m_B;
