I use this to split string by a delim.
The first puts the results in a pre-constructed vector,
the second returns a new vector.
#include <string> #include <sstream> #include <vector> using namespace std; vector<string> &split(const string &s, char delim, vector<string> &elems) { stringstream ss(s); string item; while (getline(ss, item, delim)) { elems.push_back(item); } return elems; } vector<string> split(const string &s, char delim) { vector<string> elems; split(s, delim, elems); return elems; }
Note that this solution does not skip empty tokens, so the following will find 4 items, one of which is empty:
vector<string> x = split("one:two::three", ‘:‘);
