Perimeter Calculator

Question

I have coded this program below, it works perfectly through my VS Code, but it doesn't here in this platform. As the test case is hidden, I can't figure why that is not passing. Does anyone have a clue?

Add an abstract method Perimeter to class Figure in order to calculate the perimeters of given objects.

class Program
{
static void Main(string[] args)
{
Figure rectangle = new Rectangle(5, 6);
Figure triangle = new Triangle(4, 8, 3);

Console.WriteLine(rectangle.Perimeter());
Console.WriteLine(triangle.Perimeter());
}
}
abstract class Figure
{
//define abstract method Perimeter with no body
public abstract int Perimeter();

}
class Rectangle : Figure
{
public int width;
public int height;
public Rectangle(int width, int height)
{
this.width = width;
this.height = height;
}
//override Perimeter method for rectangle
public override int Perimeter() {
return (width * width) + (height * height);
}
}
class Triangle : Figure
{
public int side1;
public int side2;
public int side3;
public Triangle(int s1, int s2, int s3)
{
this.side1 = s1;
this.side2 = s2;
this.side3 = s3;
}

//override Perimeter method for triangle
public override int Perimeter() {
return side1 + side2 + side3;
}
}

Answer 1

The formula used for rectangle perimeter needs attention. It should be the sum of the four sides, not the sum of squares of two sides. Try 2*(width + height).

I Got an Answer by this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
Figure rectangle = new Rectangle(5, 6);
Figure triangle = new Triangle(4, 8, 3);

Console.WriteLine(rectangle.Perimeter());
Console.WriteLine(triangle.Perimeter());
}
}
abstract class Figure
{
public abstract int Perimeter();
//define abstract method Perimeter with no body

}
class Rectangle : Figure
{
public int width;
public int height;
public Rectangle(int width, int height)
{
this.width = width;
this.height = height;
}
public override int Perimeter()
{
return (2*width)+(2*height);
}
//override Perimeter method for rectangle

}
class Triangle : Figure
{
public int side1;
public int side2;
public int side3;
public Triangle(int s1, int s2, int s3)
{
this.side1 = s1;
this.side2 = s2;
this.side3 = s3;
}
public override int Perimeter()
{
return side1+side2+side3;
}
//override Perimeter method for triangle

}
}

Why doesn't it work?

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
Figure rectangle = new Rectangle(5, 6);
Figure triangle = new Triangle(4, 8, 3);

Console.WriteLine(rectangle.Perimeter());
Console.WriteLine(triangle.Perimeter());
}
}
abstract class Figure
{
public abstract void Perimeter();

}
class Rectangle : Figure
{
public int width;
public int height;
public Rectangle(int width, int height)
{
this.width = width;
this.height = height;
}
public override void Perimeter(){
return (2*width)+(2*height);
}

}
class Triangle : Figure
{
public int side1;
public int side2;
public int side3;
public Triangle(int s1, int s2, int s3)
{
this.side1 = s1;
this.side2 = s2;
this.side3 = s3;
}

public override void Perimeter(){
return s1+s2+s3;
}

}
}

Answer 4

You were right man, thanks a bunch!

Answer 5

You're welcome!

Answer 6

Annoying when you cant see the results or errors.

Answer 7

U forgot the public keyword in Figure
