Thread: 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;

}

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.

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

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

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