Question

So I’m trying to fill a char array with user input. However I do not want to specify the length of the array myself, thus limiting the user to the amount they can input. For example my code below will only allow the user to enter 5 characters and then will exit. Code in any language would be fine. (The below is C#).

Console.Write("Enter a number of characters of your choice...click 1 to exit: ");
bool exitCondition;
int counter = 0;
char[] character = new char[5]; 
do
{
    exitCondition = false; 
    try
    {
        character[counter] = char.Parse(Console.ReadLine());
        if (character[counter] == '1')
            exitCondition = true; 
    }
    catch (Exception ex)
    {
        Console.WriteLine("Error: {0}", ex.Message); 
    }
    counter++;
}
while (exitCondition == false && counter < 5);

You need to use a collection, which allows the collection of elements to grow or shrink. In Java an ArrayList would be appropriate for your scenario. In C# you would most likely use a List.

C#

List<char> list = new List<char>();
list.Add('a');
list.Add('b');

Java

List<Character> list = new ArrayList<Character>();
list.add('a');
