求立方体面积体积以及判断（c++）

 代码：

#include<iostream> using namespace std;  class Cube { public: 	void setL(int l) 	{ 		m_L = l; 	} 	int getL() 	{ 		return m_L; 	} 	void setW(int w) 	{ 		m_W = w; 	} 	int getW() 	{ 		return m_W; 	} 	void setH(int h) 	{ 		m_H = h; 	} 	int getH() 	{ 		return m_H; 	}  	int calculateS() 	{ 		return 2 * (m_L + m_W + m_H) ; 	}  	int calculateV() 	{ 		return m_L * m_W * m_H ; 	}  	bool isSameByClass(Cube &c) 	{ 		if (m_L == c.getL() && m_W == c.getW() && m_H == c.getH()) 		{ 			return true; 		} 		else 			return false;  	}  private: 	int m_L; 	int m_W; 	int m_H;	 };  bool isSane(Cube &c1, Cube &c2) { 	if (c1.getL() == c2.getL() && c1.getW() == c2.getW() && c1.getH() == c2.getH()) 	{ 		return true; 	} 	else 		return false; }  int main() { 	Cube c1; 	c1.setL(1); 	c1.setW(2); 	c1.setH(3); 	cout << "第一个立方体的长为：" << c1.getL() << endl; 	cout << "第一个立方体的宽为：" << c1.getW() << endl; 	cout << "第一个立方体的高为：" << c1.getH() << endl; 	cout << "第一个立方体的面积为：" << c1.calculateS() << endl; 	cout << "第一个立方体的体积为：" << c1.calculateV() << endl; 	 	Cube c2; 	c2.setL(1); 	c2.setW(2); 	c2.setH(3); 	cout << "第二个立方体的长为：" << c2.getL() << endl; 	cout << "第二个立方体的宽为：" << c2.getW() << endl; 	cout << "第二个立方体的高为：" << c2.getH() << endl; 	cout << "第二个立方体的面积为：" << c2.calculateS() << endl; 	cout << "第二个立方体的体积为：" << c2.calculateV() << endl;  	 	bool end1 = isSane(c1, c2); 	if (end1) 	{ 		cout << "相等" << endl; 	} 	else 		cout << "不相等" << endl; 	 	bool end2 = c1.isSameByClass(c2); 	if (end2) 	{ 		cout << "相等" << endl; 	} 	else 		cout << "不相等" << endl;  	system("pause"); 	return 0; }
