Question

Examine the following code. Is there any problem according to design by contract? If yes, please list the problem(s).

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace DesignByContractDemo

{

    class Program

    {

        static void Main(string[] args)

        {

            Console.WriteLine("Please input numerator:");

            int numerator = int.Parse(Console.ReadLine());

            Console.WriteLine("Please input denominator:");

            int denominator = int.Parse(Console.ReadLine());

            Division d = new Division(numerator, denominator);

            if (denominator == 0)

                Console.WriteLine("Result = {0} ", double.PositiveInfinity);

            else

                Console.WriteLine("Result = {0} ", d.Divid());

            Console.ReadKey();

        }

    }

    class Division

    {

        double numerator;

        double denominator;

        public Division(double _numerator, double _denominator)

        {

            numerator = _numerator;

            denominator = _denominator;

        }

        public double Divid()

        {

            if (denominator != 0)

                return numerator / denominator;

            else

                return double.PositiveInfinity;

        }

    }

}

Explanation / Answer

Numerator and Denominator are being taken as Integer which violates the Contract


We cannot divide double/double

Or Double/Integer because Numnerator and denominator are being input as Integer which could be wrong.


Thanks, let me know if there is any concern.
