C++ :: Eliminate Comma And Split String Into Individual String Variables

I have this string d ="3 J JD, K" and i want to split the string to individual string. I have this code which eliminates the comma but doesn't split the string into individual string.

#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main() {
string str = "3 J JD,K";
stringstream ss(str);

[Code] ....

Output of the code is
3 J JD
k

but I want
3
J
JD
K

Also after I split the string is there any way to put the split string into individual string variables.
