std::vector is a resizable array class.

e.g.

typedef std::vector<std::string> strings;

strings tokenize(const char *line)
{
    strings res;
    ...
    res.push_back(str);
    ...
    return res;
}

strings r = tokenise("echo \"foo bar\" wiz");
assert(r.size() == 3);
assert(r[0] == "echo");
assert(r[1] == "foo bar");
assert(r[2] == "wiz");
