C++在线求大神去解 ,,,按照下图开发形状类ShApE的层次结构

class Shape { public: virtual void print() = 0; }; class TwoDimensionalShape : public Shape { }; class ThreeDimensionalShape : public Shape {}; class Circle : public TwoDimensionalShape {}; class Square: public TwoDimensionalShape {}; class

class Shape{public:Shape();virtual ~Shape();virtual void draw() = 0;virtual void resize() = 0;private:};Shape::Shape(){}Shape::~Shape(){}class Point : public Shape{public:Point();virtual ~Point();virtual void draw();virtual void resize();private:};Point::Point

#include using namespace std;#define PI 3.14enum Colors{ Black, White, Orange, Blue // etc};class Shape{public: inline int Color() const {return color;} void SetColor(int color) {this->color = color;} virtual double Area() const=0;private: int color;};

#include <iostream>#include <cmath> using namespace std; class Shape{ public: virtual double area()=0; }; class Triangle:public Shape{ double a,b,c; public: Triangle(double x=1,double y=1,double z=1){ a=x; b=y; c=z; } double area(){ double p; p=(a

#include#includeusing namespace std;const double PI=3.1415927;class Shape{public: virtual double area()=0;};class Circle : public Shape{ double radius;public: Circle(double r=1){ radius=r; } double area(){ return PI*radius*radius; }};class Square :

示例代码:#include<iostream>#include<cmath> using namespace std; const double PI=3.14; class Shape//抽象类 { public: virtual void Area()=0;//纯虚函数 }; class Rectangle:public Shape //继承方式必须为public { public: Rectangle(int a1,int b1)

class Person {};class Employee: public Person {};class Contractor: public Person {};class WagedEmployee: public Employee {};class SalariedEmployee: public Employee {};建议你买本c++的书,薄一点的,把上面的知识点多看几遍,这些东西就明白了

class Shape{public: virtual double area() const = 0;};class Square : public Shape{private: float l, w;public: Square(float len, float wid): l(len), w(wid) {} double area() const { return l * w; }};class Trapezoid : public Shape{private: float tw, bw, h;public:

#include using namespace std;void main(){ int i, j; int k = 1; for (i = 7; i>0; i -= 2) { cout0; j--) { cout } cout k ; } getchar(); return;}.

0v0这是我们期末考试的题目#include<iostream.h> #include<math.h> class Shape{ public: virtual float Area()=0; virtual void printArea()=0;};class Circle{ float radius; public: Circle(float r) { radius=r; } float Area() { return radius*radius*3.
