Question

In c++, Can anyone make these code int user input as user have to put all the amount.

int main()
   {
       Polygon p1(3,4,4.5,5.5);
       Polygon p2(4,4,5.5,6.5);
       Polygon p3(5,4,6.5,7.5);
      
       cout<<"Area of Polygon#1:"<<p1.getArea()<<endl;
       cout<<"Perimeter of Polygon#1:"<<p1.getPerimeter()<<endl;
      
       cout<<"\nArea of Polygon#2:"<<p2.getArea()<<endl;
       cout<<"Perimeter of Polygon#2:"<<p2.getPerimeter()<<endl;
      
       cout<<"\nArea of Polygon#3:"<<p3.getArea()<<endl;
       cout<<"Perimeter of Polygon#3:"<<p3.getPerimeter()<<endl;
      
      
      
   return 0;  
   }

Dear student, I have modified the code according to your requirements.
Please upvote if you are satisfied with the answer.
Please do comment below if you have any doubts thanks.


int main()
{

float a,b,c,d,e,f,g,h,i,j,k,l;

cout<<"Enter the values for Plogon 1: ";
cin>>a>>b>>c>>d;

cout<<"Enter the values for Plogon 2: ";
cin>>e>>f>>g>>h;

cout<<"Enter the values for Plogon 3: ";
cin>>i>>j>>k>>l;



Polygon p1(a,b,c,d);
Polygon p2(e,f,g,h);
Polygon p3(i,j,k,l);
  
cout<<"Area of Polygon#1:"<<p1.getArea()<<endl;
cout<<"Perimeter of Polygon#1:"<<p1.getPerimeter()<<endl;
  
cout<<"\nArea of Polygon#2:"<<p2.getArea()<<endl;
cout<<"Perimeter of Polygon#2:"<<p2.getPerimeter()<<endl;
  
cout<<"\nArea of Polygon#3:"<<p3.getArea()<<endl;
cout<<"Perimeter of Polygon#3:"<<p3.getPerimeter()<<endl;
  
  
return 0;
}
