Q&A Program with Arrays

Hi I'm currently learning C# and wanted to know how to create an Array for the below Q&A.

It's a simple q&a program i'm attempting to write in order to develop my skills in C#. Thanks!

 Console.WriteLine("What's your favorite baseball team? ");
        string baseball = Console.ReadLine();

        Console.WriteLine("How old are you? ");
        string age = Console.ReadLine();

        Console.WriteLine("Where do you live? ");
        string home = Console.ReadLine();

        Console.WriteLine("Aside from Baseball, what other sports do you love? ");
        string sports = Console.ReadLine();
    }

You can add the items to an array on its initialization like this:

string[] myArray = {baseball, age, home, sports};

Or you can initialize the array and then add the items to it like this:

string[] myArray = new string[4];
myArray[0] = baseball;
myArray[1] = age;
myArray[2] = home;
myArray[3] = sports;

However, as stated in the answer above, its better to use a generic list that will expand based on your needs (you don't have to indicate the maximum number of elements when initializing it), like this:

List<string> myList =  new List<string> { baseball, age, home, sports };

or like this:

List<string> myList =  new List<string>();
myList.Add(baseball);
myList.Add(age);
myList.Add(home);
myList.Add(sports);

The beautiful part of the list is that you can add later other elements and it will expand automatically, for example:

myList.Add("Another response will go here");

Also generic collections are faster.

I'm assuming that you simply want to store the results from these operations within an array. If that is the case, then you would simply need to instantiate a new array that would hold each of your responses :

string[] answers = new string[3];

Console.WriteLine("What's your favorite baseball team? ");
string baseball = Console.ReadLine();
// Store your first answer in the first index of the array
answers[0] = baseball;

Console.WriteLine("How old are you? ");
string age = Console.ReadLine();
// Store your age in the second index, etc.
answers[1] = age;

// Continue with your other questions here

or you could simply build the array at the end after you have all of your variables : 

string[] answers = { baseball, age, ... };

You could then reference these value by their index within your array :

string sentence = "I am " + answers[1] + " years old";

If you needed store your items within a collection that could size dynamically to fit your needs, you might consider using a List, likewise if you needed to reference your values by their name (e.g. "baseball", "age", etc.), then you could use a Dictionary.
