Split a string by a given delimiter

 I was really amazed to find out that C++ string class has no split method. There are plenty of accasions I needed to split a string by a given delimiter. Lets see how to split a string and put substrings in a to vector. 

	vector<string> split(const string &str, const char delim) {
	vector<string> tokens;
	string::size_type start = 0;
	string::size_type end = 0;
	while ((end = str.find(delim, start)) != string::npos) {
	tokens.push_back(str.substr(start, end - start));
	start = end + 1;
	}
	tokens.push_back(str.substr(start));
	return tokens;
	}

If you think incrementing varable start is ugly, you can use function find_first_not_of for it

	vector<string> split(const string &str, const char delim) {
	vector<string> tokens;
	string::size_type start = 0;
	string::size_type end = 0;
	while ((start = str.find_first_not_of(delim, end)) != string::npos) {
	end = str.find(delim, start);
	tokens.push_back(str.substr(start, end - start));
	}
	return tokens;
	}
