Question of the day....

[Thomas Freudenberg]

Following code I am using. It's a modificated version of http://gcc.gnu.org/onlinedocs/libstdc++/21_strings/stringtok_std_h.txt [Paul]

template <typename outit>
void tokenize (outit x, const std::tstring &in, const TCHAR * delimiters = _T(" \t\n"))
{
const std::tstring::size_type len = in.length();
std::tstring::size_type i = 0;

while ( i < len )
{
	// eat leading whitespace
	i = in.find\_first\_not\_of (delimiters, i);
	if (i == std::tstring::npos)
		return;   // nothing left but white space

	// find the end of the token
	std::tstring::size\_type j = in.find\_first\_of (delimiters, i);

	// push token
	if (j == std::tstring::npos) {
		\*x = in.substr(i);
		++x;
		return;
	} else {
		\*x = in.substr(i, j-i);
		++x;
	}

	// set up for next loop
	i = j + 1;
}

}

Example:

std::liststd::string ls;
utl::tokenize (std::back_inserter(ls), " this \t is\t\n a test ");
for (std::list::const_iterator it = ls.begin(); it != ls.end(); ++it)
{
std::cerr << ':' << (*it) << ":\n";
}

would produce following output:

:this:
:is:
:a:
:test:

Do you fancy coming up with a few lint-type questions? [what do you do if you have an inny type button] Alice thought that running very fast for a long time would get you to somewhere else. " A very slow kind of country!" said the queen. "Now, here , you see, it takes all the running you can do, to keep in the same place".
