[C++] split string by string

using namespace std;

template<typename T>
split(const T & str, const T & delimiters, vector<T>& result) {
vector<T> v;
T::size_type start = 0;
auto pos = str.find(delimiters, start);
while(pos != T::npos) {
if(pos != start) // ignore empty tokens
v.emplace_back(str, start, pos - start);
start = pos + delimiters.length();
pos = str.find(delimiters, start);
}
if(start < str.length()) // ignore trailing delimiter
v.emplace_back(str, start, str.length() - start); // add what's left of the string
return v;
