急！！请C++编程高手帮忙编个程序

采用面向对象的程序编写一个圆类circle和一个桌子类table,另设计一个圆桌类roundtable,它是从前两个类派生的，要求输出一个圆桌的高度，面积和颜色等数据

#include <iostream>

using namespace std;

class circle {
protected:
double r;

public:
circle(double _r) {r = _r;}
double getArea() {return r * r * 3.14;}

};

class table {
protected:
double h;
int color;
public:
table(double _h, int _color) {
h = _h;
color = _color;
}
double getHight() {return h;}
int getColor() {return color;}
};

class roundtable:public circle, public table {
public:
roundtable(double _r, double _h, int _color):circle(_r), table(_h, _color) {}
};

int main() {
roundtable onetable(10.0, 10.0, 1);

cout<<"高度："<<onetable.getHight()<<endl;
cout<<"面积："<<onetable.getArea()<<endl;
cout<<"颜色："<<onetable.getColor()<<endl;

return 0;
}
