Enhanced Complexnumber Class C# Sharp Exercise


Enhanced Complexnumber Class


Improve the "ComplexNumber" class, so that it overloads the operators + and - to add and subtract numbers.

Example Code

using System;
class ComplexNumber
    protected double a, b;

    public ComplexNumber(double realPart, double imaginaryPart)
        a = realPart;
        b = imaginaryPart;

    public double GetReal()
        return a;

    public void SetReal(double a)
        this.a = a;

    public double GetImaginary()
        return b;

    public void SetImaginary(double b)
        this.b = b;

    public new string ToString()
        return "(" + a + "," + b + ")";

    public double GetMagnitude()
        return Math.Sqrt((a * a) + (b * b));

    public void Add(ComplexNumber c2)
        a += c2.GetReal();
        b += c2.GetImaginary();


class ComplexTest
    static void Main()
        ComplexNumber number = new ComplexNumber(5, 2);
        Console.WriteLine("Number is: " + number.ToString());

        Console.WriteLine("Number is: " + number.ToString());

        Console.Write("Magnitude is: ");

        ComplexNumber number2 = new ComplexNumber(-1, 1);
        Console.Write("After adding: ");
