Answer to Question #166911 in C# for Habib

Question

Complete the project named "Shapes", adding a class named "Square" to it. For each square, we will store its starting X and Y coordinates (the upper left corner, already stored as a "Location") and the length of its side.

You will have to create:

- A suitable constructor, to assign starting values to X, Y and the side. (2 points)

- A Move method, to change X and Y coordinates. (1 point)

- A Scale method, to change its side (for example, a scale factor of 2 would turn a side of 3 into 6). (1 point)

- A method ToString, to return a string with its data (for example: "Corner (10,5), side 7". (1 point)

- Redefine "GetPerimeter" and "GetArea", so that they return the correct values (2 points).

- Another point corresponds to the attributes and the overall structure.

- The remaining 2 points correspond to the test from "Main"

Answer 1

class Program
    {
        public class Square
        {
            private double X_Coordinate;
            private double Y_Coordinate;
            private double side;


            public Square(double X_Coordinate, double Y_Coordinate, double side)
            {
                this.X_Coordinate = X_Coordinate;
                this.Y_Coordinate = Y_Coordinate;
                this.side = side;
            }


            public void Move(double X, double Y)
            {
                X_Coordinate += X;
                Y_Coordinate += Y;
            }
            public void Scale(double scaleFactor)
            {
                side *= scaleFactor;
            }
            public override string ToString()
            {
                return string.Format("Corner({0},{1}) side {2}", X_Coordinate, Y_Coordinate, side);
            }
            public double GetPerimeter()
            {
                return 4 * side;
            }
            public double GetArea()
            {
                return side * side;
            }
        }
        static void Main(string[] args)
        {
            Square square = new Square(10, 5, 7);
            Console.WriteLine(string.Format("Square: {0}",square));
            square.Move(1, 2);


            Console.WriteLine(string.Format("Square: {0}", square));
            square.Scale(2);
            Console.WriteLine(string.Format("Square: {0}", square));


            Console.WriteLine(string.Format("Perimeter: {0}", square.GetPerimeter()));
            Console.WriteLine(string.Format("Area: {0}", square.GetArea()));
            Console.ReadKey();
        }
    }
