Separate sentences into words with string and arrays

[xephia]

Hey all, I am resorting to posting this question after getting absolutely nowhere in four days of searching (except for maybe negative steps, got mad at my laptop and broke my delete key :( )


Anyway, my problem is that I need to separate sentences into words. I figure that the only logical way of doing this would be to use an array (and I need to for other parts of this program which I have already made)

However, I can't figure out how to gut the sentence into spaces using a loop that will pick up on the space, and put the word into one element and then start again and put the next into the next element.

So far i have tried this code, but i doubt its helpful.

do
{
    for(i=0;int(word1.length());i++)
  {
    nextchar=word1.at(i);//get char

if(nextchar!=' ')
  {
    for(i=0;i<MAX;i++)
          nextchar=word[i];
}
}
}

while(nextchar!='.');

Anyway, I know theres probably some errors in the formatting and spelling and stuff in that, but thats my latest concoction of how to possibly do it, I know its wrong :(

Please help, I will pray for whoever helps me tonight before i go to sleep ;)

THANKS in advanced for ANY help... but if you can give me a snippet of code it would be greatly appreciated.

Once you have the entire string the user enters, doesn't it make sense that a word would lie between two spaces? You can consistantly search for a space in the whole sentence, and then set word equal to the proper substring of the sentence. You might need a function that will clear the spaces from in front of a word, and you will call this function before every iteration of your loop - which should be a while loop, with the condition that the sentence's length is not 0.

If you still have trouble, go ahead and ask - I recently did a similar program and will have access to the code Monday-Friday (I have it saved at school).

If you could give me that code it would be great for a starting point


I'm still stuck, this is soo frusturating

I'll give you the first half of my code: the main() and the function prototypes. But I'm leaving it up to you to write the function bodies. Otherwise, you wouldn't learn anything.

/* Chapter 8 Worksheet Program 2
Independent Study, Michael Stark */

#include<iostream>
#include<string>
using namespace std;

void extractFirstWord(string& sentence, string& word);
void processBlanks(string& sentence);

int main() {
    string sentence, word;
    cout << "Input a sentence: ";
    getline(cin, sentence);
    
    while (sentence != "") {
          processBlanks(sentence); // removes all blanks from the front of sentence
          if (sentence.length() > 0) { // removing blanks may have made sentence null - cannot extract from a null string
             extractFirstWord(sentence, word); // gets first word from sentence and puts into word
             cout << word << endl; // output one word at a time
          }
    }
    
    system("PAUSE");
    return 0;
}

void extractFirstWord(string& sentence, string& word);
// extractFirstWord removes the substring of sentence 
// from the beginning to the first space from sentence 
// and stores the same string into word. sentence is
// shortened accordingly.
// Postcondition: sentence is shortened, and word
//                is appropriately the first word in
//                sentence.

void processBlanks(string& sentence);
// processBlanks will remove all of the spaces in front
// of sentence.
// Postcondition: sentence has no spaces in front of
//                the first word.
