如何使用多重继承执行矩形的区域和周长 [英] how to perform area and perimeter of rectangle using multiple inheritance

问题描述

怀疑是关于是否为区域和周边编写成员函数和

我的语法如下检查是否正确

The doubt is about whether to write member functions for area and perimeter and
my syntax is as follows check whether it is right

#include <iostream.h>
#include<conio.h>
class Area
{
  public:
    float area(float l,float b)
    {
        return l*b;
    }
};

class Perimeter
{
  public:
    float peri(float l,float b)
    {
        return 2*(l+b);
    }
};

class Rectangle : private Area, private Perimeter
{
    private:
        float length, breadth;
    public:
       Rectangle() : length(0.0), breadth(0.0) { }
       void get_data( )
       {
           cout<<"Enter length: ";
           cin>>length;
           cout<<"Enter breadth: ";
           cin>>breadth;
       }

       
};

int main()
{
    Rectangle r;
    r.get_data();
    cout<<"Area = "<<r.area_calc();
    cout<<"\nPerimeter = "<<r.peri_calc();
    return 0;
}
