Rik,

are you sure your solution below works? I copied your code into my Wordscramble program and when I run it, the program works fine when I don't specify an argument and the default wordlist is loaded. But when I do specify an alternate file, the program runs but does not print out any letters nor do commands !quit, etc. work.

Any ideas???

Thanks,

Am I right in thinking what you've done is get the specified wordlist added to the default after checking that words contained in both aren't added twice?

Here's what I did which works:

Code:

class MainClass
{
   static List<string> Wordlist = new List<string>();
   static List<string> UsedList = new List<string>();
   static int score;
   static string PromptLetters;
   static Random Rand = new Random();
   public static void Main(string[] args)
   {
      if (args.Length == 0) {
      string[] lines = File.ReadAllLines("wordlist");
      foreach(string word in lines) {
         if (word.Length <3) continue;
         if (word.Contains("'")) continue;
         Wordlist.Add(word.ToLower());
         }
      } else {
         string[] lines = File.ReadAllLines(args[0]);
      foreach(string word in lines) {
         if (word.Length <3) continue;
         if (word.Contains("'")) continue;
         Wordlist.Add(word.ToLower());
         }
      }

What I wanted to do was when a file was specified as an argument it checked to see if the file existed and then used that as the word list, otherwise it would use 'Wordlist'. This seemed to work, but probably isn't the most elegant solution.

I've done mine the same as rikoshay2020.
Works fine.

What did have me pulling my hair out was on Homework 2:
score =+ input.Length;

For about an hour I was puzzled to why it didn't work.

That's right should be:
score += input.Length;

arghh!!

I worked a way for doing part 3 of the homework on assignment 2. I have copied it below. What I wanted to know is this. Is there a better way of doing this, because I seemed to take a bit of a roundabout way to the solution.

Now on to homework part 4!!

Thanks,
