Hello.

I have a string of the following format:

11, 0, 1461, 400

I need to be able to extract any element of the string at any point, so for example, the 1, would return 11, or the second world return 0. What is the best way of extracting any individual element, without using any temporary variables.

IF I use boost.tokenizer, can I access any element individually, without using iterators? Or is there a better way of dealing with this sort of string.

Looks like you want to have a vector with the tokenized elements. I'm afraid the only way of getting the results of a tokenizing operation is via iterators. However, you can easily assign the elements to a vector: #include<iostream> #include<boost/tokenizer.hpp> #include<boost/foreach.hpp> #include<string> #include <vector> int main(){ using namespace std; using namespace boost; string s = "This is, a test"; tokenizer<> tok(s); vector <string> myTokens (tok.begin(), tok.end()); BOOST_FOREACH(string & s, myTokens){ cout << s << endl; } } Hope it helps. -- José Tomás Tocino García
