Abstract Classes

Question

I'm not sure why its not working. I do exactly what it asks.
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();
}
class Rectangle : Figure
{
public int width;
public int height;
public Rectangle(int width, int height)
{
this.width = width;
this.height = height;
}
public override int Permieter()
{
return (width + height) * 2;
}
}
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 (s1 + s2 + s3);
}
}
}
This is my code, I'm suppose to add an abstract class and override it in the other classes and add the implementation.

Answer 1

Hey there, this code worked out for me:
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
{
//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(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;
}
//override Perimeter method for triangle
public override int Perimeter()
{
return(side1+side2+side3);
}
}
}

Answer 2

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace SoloLearn
{
class Program
{
abstract class Shape {
public abstract void Draw();
}
class Circle : Shape {
public override void Draw() {
Console.WriteLine("Circle Draw");
}
}
class Rectangle : Shape {
public override void Draw() {
Console.WriteLine("Rect Draw");
}
}
static void Main(string[] args)
{
Shape c = new Circle();
c.Draw();
}
}
}
Its the same exact thing as the practice?
This is pretty bad.
Why dont you have any tests made to tell me whats wrong?

Answer 3

its because of the values being pushed through the paremeters and being stored as a different variable
