'strtok' returns tokens in the string. Basically you put it in a loop, give the input string and a delimiter as arguments, it'll keep returning each token. you can put a counter and check for NULL token to exit the loop. for function signature try reading some doc.

and yes make sure you read the 'things to keep in mind' while using strtok or the result would be unexpected... dont want to tell you and spoil the suspense :)

It is easier to use std::stringstream class to do that

#include <sstream>
<other includes here>

...
string sentence = "Once upon a time there were three little pigs";
string word;
vector<string> array;
stringstream stream(sentence);
while( stream >> word)
{
    array.push_back(word);
}
