Hi Friends,
I am trying to get the number of words in each sentences but facing some difficulties. I have to find the most number of repeated words in each sentence as well as in paragraph. So friends I need your help.

My code:

#include "stdafx.h"
#include "iostream"
#include "string"
#include "sstream"

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
	string userInput="India is a country in South Asia. It is the Seventh-Largest country by area and second-largest by population and most populous democracy in the world.";
	int words = 1;     
	int sentences = 0;
	int paragraphs = 1;

	//cout << "Enter some text: ";
	//getline (cin, userInput);

	for (int i = 0; i < int(userInput.length()); i++) 
    { 		
		if (userInput.empty()) 
		{
			words--;
			paragraphs--;
		}

		if (userInput[i] == ' ')  
			words++ ;

		if (userInput[i] == '.')
			sentences++;
			

		if (userInput[i] == '\n' && userInput[i] == '\t')
			paragraphs++;
    }
	cout << "words: " << words << endl;
	cout << "sentences: " << sentences << endl;
	cout << "paragraphs: " << paragraphs << endl;

	//cout << "Number of words in sentence :" << endl;
	
	/*
     istringstream iss(userInput);
       do
       {
         string sub;
         iss >> sub;
         cout << "Substring: " << sub << endl;
       } 
	while (iss);*/

	return 0;
}

Advance Thanks

I think you are right. Stinks of homework and there isn't even a question here.

Why don't you ask some specific questions about problems you can't solve. Its less likely that someone will give you a full solution despite the fact that this is an easy task. If you don't like programming, you are taking the wrong course.

If it is a homework, just add corresponding tag. Anyway, try to get something useful from the sample code of S.Meyers (http://www.artima.com/samples/cpp11NotesSample.pdfList the 20 most common words in a set of text files). Though, you will have to adapt it for own needs because, i guess, your teacher would not believe you wrote it by yourself.

well my solution exactly answers your question. I have code in java so if u might able to understand it its good. My solution will display top ten most repeated words in each paragraph...

here is a glimpse of code to find original solution visit

Java

for (int i = keys.length - 1, count = 0; i >= 0; i--)
            {
                if (count == 10) {
                    break;
                }
                count++;
                System.out.println(count + ". " + keys[i] + ",    \tFrequency "+ map1.get(keys[i]));
            }

Assuming well-formed text (single space between words, full stop at end of a sentence, newline at end of a paragraph), declare an empty dictionary with with key = word and record = pair of per-sentence word count, per-paragraph word count. Use the following single-pass scan:

for each character:
    if space, full stop or newline: (finishing a word)
        insert the word just seen in the dictionary, if need be; increment its per-sentence and per-paragraph counts

    if full stop or newline: (finishing a sentence)
        output the largest per-sentence word count; clear all per-sentence word counts

    if newline: (finishing a paragraph)
        output the largest per-paragraph word count; empty the dictionary

1. Try writing three different functions, one each for counting words, sentences, and paragraphs. You may have to duplicate some code, but by separating the the three tasks you will have an easier time to test for the correct conditions, and you will be able to solve one problem at a time.

2. It's a good idea to initialize variables when you define them, but you should use reasonable values. I understand your reasons to initialize some with 1 instead of 0, but it definitely looks odd, and makes it harder to understand your code and follow its logic.

3. Your test for blanks does not consider other cases of 'whitespace', such as tab characters, carriage return, form feed, or multiple whitespace characters. It may not apply to the case you are testing here, but if you base your code only on the specific test case you have, you may as well count the words by hand and return these numbers rather than write an entire algorithm around it...

4. '.' is not the only way to end a sentence. Also, depending on where you get your text from, you may be confronted with sequences of multiple punctuation marks!!! ;-)

5. The condition

C++

if (userInput[i] == '\n' && userInput[i] == '\t')

is always false and always will be, no matter the text. Besides, why do you test for a tab character ( '\t' )? Reconsider the definition of paragraph that you use, or, rather, the definition of what separates paragraphs.

6. As a general rule, always consider corner cases: e. g. multiple separater characters where you only expect one, omitting or adding a separator at the end of the text, using variants on the commonly used separators, or interpreting characters that are not part of the readable text, but not one of the separators you catch either.
