Question

I'm trying to construct this program in C#, I found some similiar problems in Java but as a beginner, its not very easy to follow along with the Java code.

Create a Console application named RelativesApp to help you remember your relatives’ birthdays.

·Create a Relative class that includes auto-implemented properties for the relative's name, their relationship to you, and two integers to represent their birthday –month, day.

·Declare an array of at least 12 relative objects.

·Fill the array with relatives of your choice.

·Display the contents of the array using a for loop

·Using Sort(), sort the array by month and day

·Display the contents again.

·Using BinarySearch(), search to see if anyone has a birthday on a particular day of the month and display an appropriate message such as: “Ruby’s birthday falls on 11/17!”or“Nobody’s birthday falls on 11/20”

Answer 1

Below is the code as per the requirements. It is well explained inside the code using comments:

using System;

namespace RelativesApp
{
    // Relative class
    class Relative : IComparable
    {
        public string Name { get; set; }            // relative name
        public string Relationship { get; set; }    // relationship
        public int BirthdayMonth { get; set; }      // birthday month
        public int BirthdayDate { get; set; }       // birthday date

        // constructor
        public Relative(string n, string r, int mm, int dd)
        {
            Name = n;
            Relationship = r;
            BirthdayMonth = mm;
            BirthdayDate = dd;
        }

        // compare to method for sorting
        public int CompareTo(object obj)
        {
            Relative otherRelative = (Relative)obj;

            int result = BirthdayMonth.CompareTo(otherRelative.BirthdayMonth);

            // if months are equal
            if (result == 0)
                result = BirthdayDate.CompareTo(otherRelative.BirthdayDate);

            return result;
        }
    }

    // main class
    class Program
    {
        // main method
        static void Main(string[] args)
        {
            // declare array of 12 relative objects
            Relative[] relatives = new Relative[12];

            // fill the content
            relatives[0] = new Relative("Percy Shoemaker", "uncle", 5, 12);
            relatives[1] = new Relative("Williemae Milici", "father", 2, 10);
            relatives[2] = new Relative("Nicky Lemmons", "son", 1, 8);
            relatives[3] = new Relative("Darius Dangerfield", "daughter", 7, 2);
            relatives[4] = new Relative("Alba Maricle", "mother", 10, 9);
            relatives[5] = new Relative("Ralph Connally", "grand mother", 7, 23);
            relatives[6] = new Relative("Chester Crownover", "grand son", 6, 11);
            relatives[7] = new Relative("Elfrieda Oconnor", "grand daughter", 3, 16);
            relatives[8] = new Relative("Vada Scarlett", "daughter", 2, 25);
            relatives[9] = new Relative("Collette Symons ", "niece", 8, 28);
            relatives[10] = new Relative("Jonah Askew", "nephew", 12, 19);
            relatives[11] = new Relative("Norma Mccrary", "mother", 8, 17);

            // display the array contents
            display(relatives);

            // sort the array
            Array.Sort(relatives);

            // display the array contents again
            Console.WriteLine("Sorted:");
            display(relatives);

            // search for birthday 7/23
            int index = Array.BinarySearch(relatives, new Relative("", "", 7, 23));

            // display the name, if birthday found
            if (index >= 0)
                Console.WriteLine("\n" + relatives[index].Name + "'s birthday falls on " + relatives[index].BirthdayMonth + "/" + relatives[index].BirthdayDate + "\n");
            else
                Console.WriteLine("\nNobody's birthday falls on " + relatives[index].BirthdayMonth + "/" + relatives[index].BirthdayDate + "\n");
        }

        // displays the content of array
        private static void display(Relative[] relatives)
        {
            Console.WriteLine();
            for (int i = 0; i < 12; i++)
            {
                Console.WriteLine("Name: " + relatives[i].Name + ", Relationship: " + relatives[i].Relationship + ", Birthday: " + relatives[i].BirthdayMonth + "/" + relatives[i].BirthdayDate);
            }
            Console.WriteLine();
        }
    }
}

Below is the sample output:

Name : Nicky Lemmons. Relationship: son, Birthday: 1/8 Name : Darius Dangerfield, Relationship: daughter, Birthday: 7/2 Name: Alba Maricle, Relationship: mother, Birthday: 10/9 Name: Ralph Connally. Relationship: grand mother, Birthday: 7/23 Name : Chester Crownover, Relationship: grand son, Birthday: 6/11 Name : Elfrieda Oconnor, Relationship: grand daughter, Birthday: 3/16 Name : Vada Scarlett, Relationship: daughter. Birthday: 2/25 Name: Collette Symons. Relationship: niece, Birthday: 8/28 Name : Jonah Askew, Relationship: nephew, Birthday: 12/19 Name : Norma Mccrary. Relationship: mother. Birthday: 8/17 Sorted: Name : Nicky Lemmons, Relationship: son, Birthday: 1/8 Name: Williemae Milici. Relationship: father. Birthday: 2/10 Name : Vada Scarlett, Relationship: daughter. Birthday: 2/25 Name: Elfrieda Oconnor, Relationship: grand daughter. Birthday: 3/16 Name : Percy Shoemaker. Relationship: uncle, Birthday: 5/12 Name : Chester Crownover, Relationship: grand son, Birthday: 6/11 Name : Darius Dangerfield. Relationship: daughter. Birthday: 7/2 Name : Ralph Connally, Relationship: grand mother. Birthday: 7/23 Name : Norma Mccrary, Relationship: mother. Birthday: 8/17 Name: Collette Symons Relationship: niece, Birthday: 8/28 Name: Alba Maricle, Relationship: mother. Birthday: 10/9 Name: Jonah Askew, Relationship: nephew, Birthday: 12/19 Ralph Connally's birthday falls on 7/23

This completes the requirement. Let me know if you have any queries.

Thanks!
