Programming Code:

[Aaaaaaaaa]

 Write a program to alphabetize a list of last names. The user will input an undetermined number of last names. The program will display the number of names entered and alphabetized lists of the names in ascending (A-Z) and descending (Z-A) order.

 

Your program will store the names in an ArrayList object. It will use various ArrayList properties and methods to implement the program requirements.

Sample output:

 

Enter a last name: Roberts

Keep going? (Y/N): y

Enter a last name: DeLay

Keep going? (Y/N): y

Enter a last name: Foreman

Keep going? (Y/N): y

Enter a last name: Ganguly

Keep going? (Y/N): n

 

4 last names entered

 

Names in Ascending Order

 

DeLay

Foreman

Ganguly

 

Names in Descending Order

 

Roberts

Ganguly

Foreman

DeLay

 

 

Don't try to write too much at a time! First, write an outline in comments based on the requirements and the pseudocode. Then, work on instantiating an ArrayList object, followed by implementing the loop that will get user input. As always, keep things simple and implement incrementally. Review the list of ArrayList methods and properties in the textbook and experiment with the ones you think you'll need.

Pseudocode

 

Main function

Instantiate ArrayList object

Loop to get last names, until user wants to quit

Add each last name to the ArrayList

Display the count of the last names

Sort the ArrayList

Loop to display the names

Reverse the order of the ArrayList

Loop to display the names

 

 

Above is the question^

 

 

 

 

Below is what I have started working on but the names wont process in ascending and descending order. Please help me???

 

 

 

 

            var names = new List<String>();

 

            do

            {

                Console.Write("\nEnter name: ");

                names.Add(Console.ReadLine());

                Console.Write("Keep going? (y/n)");

            } while (Console.ReadKey().KeyChar == 'y');

 

            Console.WriteLine(

                  "\n{0} names entered."

                + "\nNames in ascending Order\n");

 

 

            names.Sort();

            foreach (var name in names)

            {

                Console.WriteLine(name);

            }

 

            Console.WriteLine("\nNames in descending Order\n");

 

            names.Reverse();

            foreach (var name in names)

            {

                Console.WriteLine(name);

Try this instead of Sort() :

names = names.OrderBy(x => x).ToList();

[Aaaaaaaaa]

//Initialize names listvar names = new List<String>();do{    //Get new name    Console.Write("\nEnter name: ");    names.Add(Console.ReadLine());    //Ask to continue    Console.Write("Keep going? (y/n)");}while(Console.ReadKey().KeyChar == 'y'); //Diaplay name countConsole.WriteLine("\n\n\n{0} names entered.", names.Count); //Sort names ascendingnames.Sort();//Loop through list and display namesConsole.WriteLine("\n\nNames in ascending Order: ");foreach(var name in names){    Console.WriteLine(name);} //Reverse the listnames.Reverse();//Loop through list and display namesConsole.WriteLine("\n\nNames in descending Order: ");foreach(var name in names){    Console.WriteLine(name);}//Pause console while user displays resultsConsole.ReadKey();

Thank You So Much!

You had it all done perfectly fine with just some minor errors.

Ohh Okay! I knew I was on the right track, just was not sure.
