Break Up Getline

Hello All,
Is there anyway to break up getline by 'spaces' and insert each word into a vector?
I have the user stop at '.'. My code is as follows - it just inserts the whole string into a vector.

How would I get something if the user types in this:
Break Me Up.

into a vector (separated by words) like this

Break
Me
Up

Any help greatly appreciated! - pandadc

Code:

int main()
{
   vector< string > texts;

   string usertext;

   cout << "Please enter some text." << endl;

   getline(cin, usertext, '.');


   texts.push_back(usertext);


   for (unsigned int i = 0; i < texts.size(); i++)
      cout << texts.at(i) << endl;

return 0;

}

If you wanted to do it manualy, use the .find() function to find the first space, and .sub_str() to a temp string variable. Then .;push_back() that into the texts vector.

There's something in boost that can do it though, I think.

I used this recently to do something similar. I used a * instead of a ' ' though

Code:

void GetCatagories ( std::string List, std::vector<std::string> &Catagories )
{
	if ( List != "" )
	{
		Catagories.clear();

		int 	End	= 0,
			Start	= 0;

		while ( (End = List.find( '*', Start )) != -1 ) 
		{
			Catagories.push_back( List.substr( Start, End - Start ) );
			
			Start = End+1;
		}
		Catagories.push_back( List.substr( Start, List.size() - Start ) );
	}
}

EDIT :: change GetCatagories to ParseToVector or something. Change List to ToBeParsed. And perhaps Catagories to VecSubStr or something. The names I gave made sense to my project at the time, but probably aren't suited to yours.

You can use string streams, which act like input/output streams but on given strings. You construct an input string stream with the string line that you want, then like a normal (while >> cin) loop you push back the contents of the line word by word into the vector

Code:

#include <iostream>
#include <string>
#include <sstream>
#include <vector>

using std::cout;
using std::cin;
using std::string;

using std::vector;

using std::istringstream;


int main(int argc, char *argv[])
{
	string line;
	vector<string> words;
	while(getline(cin, line))
	{
		istringstream in(line);
		string word;
		while(in >> word)
			words.push_back(word);
	}

	return 0;
}

Or pass ' ' as the delimiter to getline.

>> Or pass ' ' as the delimiter to getline.

But he wants the whole sentence, for '.' being the delimiter. Not just one word. I thought the same thing initially though

He can break the while loop when he finds a dot as the last char in the string.
The loop controls the validity of getline with ' ' as the delimiter. The if() inside checks for the dot being the last character of the string.

This is what I have so far:

Code:

cout << "Please enter some text." << endl;

   getline(cin, usertext, '.');
   int end = 0;
   int start = 0;


   end = usertext.find(" ", start);

   texts.push_back(usertext.substr(start, end - start));
   start = end + 1;

for (unsigned int j = 0; j < texts.size(); j++)
      cout << texts.at(j) << endl;

It reads in the first word perfectly... but I can't figure out how to get my if statement to move to the next word.

Any suggestions?
It reads in the

Why don't you just use my function? or any of the other suggestions posted here?

Code:

   string usertext = "";
   vector< string > vecText;

   cout << "Please enter some text." << endl;
   getline(cin, usertext, '.');

   GetCatagories ( usertext, vecText );

or something. Your example doesn't work cause you're not looping it.

awesome twomers, thanks for the help! I figured it out.
