VS2012

Hi all,

I need to create a program that shows a sentence with the most words in it.

My 3 sentences are:

I like apples. I like red apples. I like red apples than green apples.

How do I show a sentence with the most words in it?
(The result should be displaying "I like red apples than green apples")

I'm new to programming so please understand that I am not able to post my code here because I don't even know where to begin....

Thanks a lot in advance~

Solution 4

C#

// requires Linq

private string testText = @"I like apples. I like red apples. I like red apples than green apples.";

private char[] sentenceDelimiter = new char[] {'.'};

// slower: sort, O(nlogn)
private string GetLongestSort(string sentences)
{
    return
        sentences.Split(sentenceDelimiter)
            .OrderByDescending(s => s.Length).FirstOrDefault();
}

// much faster: aggregate, O(n)
private string GetLongestAggregate(string sentences)
{
    return
        sentences.Split(sentenceDelimiter)
            .Aggregate("", (lenVar, itm) => lenVar.Length > itm.Length ? lenVar: itm);
}

// test ... inside a method or EventHandler
string longest1 = GetLongestSort(testText);

string longest2 = GetLongestAggregate(testText);

Hi BillWoodruff! Thanks for the solution and the time you took to write the solution but unfortunately I have no idea about Linq.... but thanks anyway~

BillWoodruff 7-Nov-14 3:30am

You're welcome. Learning to use Linq will really help you become a better .NET developer; if you've had experience with SQL query, you'll be on familiar ground.

Sacha Barber, one of CodeProject's smartest technical minds has written a three-part introduction to Linq, DLinq, and XLinq: may I suggest you read:

http://www.codeproject.com/Articles/18116/LINQ-Introduction-Part-Of

If you have access to one of Andrew Troelsen's .NET books (3.5 or later), I think his explanations/explorations of Linq are exceptionally clear:

cheers, Bill

Hi Bill, WoW! I'm so impressed that many people are actually willing to help out a stranger! So cheesy but I wanna say the world is beautiful~ haha :D and yes! I am okay(I guess) with SQL and T-SQL query but I was chickened out coz Linq seems totally different language(maybe it is a totally different language that I need to learn from scratch) :) Thanks for the links and I'll check it out soon!

We all start at the beginning, sometime :) The LinqPad free software, and its website, created by Joseph Albahari is a very valuable resource for learning Linq:

I like Linq, +5!

BillWoodruff 7-Nov-14 3:32am

Thanks, Maciej, I appreciate Linq more and more, even though I don't yet feel that I have as clear a "mental model" of what some of the operators do, internally, as I would like. Linq is one of the focal points for my own (never-ending) self-education at this time.

Hi,

Please try the following code:

C#

public int GetNoOfWords(string s)
{
    return s.Split(new char[] { ' ', '.', ',','?' }, StringSplitOptions.RemoveEmptyEntries).Length;
}

The above code assumes space, comma, full stop, question mark as word separators and will return the word count.

And call this function like this:

C#

string text = "This is an simple example which demonstrates how to count the number words in a string using C#. This is a test string.Hence, Test it properly in c#.";
int words = GetNoOfWords(text)

Check where you get the count to be maximum.

Hope this helps !!

Regards,
Praneet

Here i have one solution and hope this will definitely match with your requirement.

Here is a method to get the maximum word containing sentence from a whole paraghraph if passed as parameter to it.

C#

private string GetSentenceWithMostWords(string strParagraph)
        {
            int iWordsCount = 0;
            string strSentenceWithMostWords = string.Empty;
            string[] arrAllSentences = strParagraph.Split(new char[] { '.' }, StringSplitOptions.RemoveEmptyEntries);
            foreach (string strSentence in arrAllSentences)
            {
                string[] arrWords = strSentence.Split(new char[] { ' ', ',' }, StringSplitOptions.RemoveEmptyEntries);
                if (iWordsCount < arrWords.Length)
                {
                    iWordsCount = arrWords.Length;
                    strSentenceWithMostWords = strSentence + ".";
                }
            }

            return strSentenceWithMostWords;
        }

Here is the form load code to call it and get the proper result to view :-

C#

private void SentenceWithMostWordsTestForm_Load(object sender, EventArgs e)
        {
            string strParagraph = "I like apples. I like red apples. I like red apples than green apples.";
            string strSentenceWithMostWords = GetSentenceWithMostWords(strParagraph);
        }

Hope this is helpful.

Solution 5

C#

string[] st = { "I like apples.", "I like red apples.", "I like red apples than green apples." };

                string result = st.OrderByDescending(s => s.Length).First();

                this.label1.Text = result;
