C# ONLY PLEASE C# ONLY C# ONLY Background:

Word guessing games are a very common childhood activity. Typically you are told how

many letters are in the word, and then you guess letters. Letter by letter, you either see

more of the word, or you run up against a deadline. Examples of these games are

apple tree, hangman, and even the TV show Wheel of Fortune.

You have decided to go try out for Wheel of Fortune, but you want to put your new found

coding skills to the test first. You are going to write a helper program, which will help

you guess the correct words.

This program will ask you how many letters are in the word, then it$$ll ask you to give it

some letters that you know, and it$$ll show you all the possible words of that length with

those letters.

There are two different ways that you might want to use it$.$ For example you might want

to find all words which have the letters o and p in them in any order. $$Top$$ being an

example, $$Pot$$ being another. But you might also want to be able to find words with a

particular pattern in them, for example, all words with $$pp$$ in them $($such as happy$).$

In order to simplify this, we are going to use a dictionary of the $900$ most common words

in English. When we get to the FileIO Module in a few weeks, you could modify this to

load in a full dictionary which would have $100,000+$ words. Then it would be even more

powerful, but even with the $900$ most common words, it$$ll help a lot.

Your tasks:

$1)$ In the zip file with these instructions, you also were given an English.java and an

English.cs file. If you are a java student you only need English.java, if you are a

C# student you only need English.cs$.$

$2)$ Import the appropriate file into your project $($either copy$/$paste$,$ or import the file$).$

You do not need to change anything in this class, so don$$t modify any code in

there.

$3)$ In your main class, write the following methods:

a$)$ wordContainsLetter. It should take in a word $($String$)$ and a letter $($char$)$

and it should return a boolean which is true if the word contains that letter,

or false if not.

There are many ways to do this, but the simplest is to use a foreach loop

that iterates over the String as if it$$s an array of characters. Both C# and

Java have a string method called toCharArray which converts a string to

an array of characters. It may be helpful.

b$)$ wordContainsString. It should take in two strings, and determine if one

string is in the other. For example if given $$happy$$ and $$pp$$ it should

return true. If given $$happy$$ and $$ab$$ it should return false. It should only

return true if the entire second string is in the first string. Both languages

have methods for doing this. Check out the docs for String objects here

and look for a useful method:

c$)$ guessWordWithLetters. It will take in an English object, a length and a

string of letters. For example, you might be passed the English Object, $3$

and $$at$.$ You$$ll then look for all words that are $3$ letters long, that have an

$$a$$ and a $$t$$ in them and print them out $($e$.$g$.$ tax, art and eat$).$ It will return

void.

What you will want to do here, is iterate over every word in the English

object$$s words list$/$arraylist$.$ As you look at each word, you$$ll decide if it$$s

the right length, then you$$ll check each of the letters that were passed in to

see if they are in the word. If it$$s the right length and all the letters are in

there, print it out, otherwise move onto the next word.

d$)$ guessWordWithPattern. It will take in an English object, a length, and a

pattern $($string$).$ For example you might be passed the English Object, $3$

and ct$.$ This will only print words which have c followed by a t in them.

Again this method returns void.

$4)$ Finally, you$$ll write a driver in your main class. It should do the following:

a$)$ Prompt the user to enter the length of the word they are looking for $$How

many letters are in the word?$$

b$)$ Read in the response.

c$)$ Prompt the user with a menu asking if they want to search for letters, or by

pattern. It should read:

Do you want me to look for letters or a pattern?

$1.$ Letters

$2.$ Pattern

d$)$ Read in the user's response. If they choose $1,$ ask them for the letters

$$What letters are in the word?$.$ Now call guessWordWithLetters, passing

the appropriate arguments. If they choose $2,$ ask for the pattern $$What

pattern is in the word?$.$ Now call guessWordWithPattern, passing the

appropriate arguments.

In either case print out $$It might be any of these...$$
