how to parse using stringstream

#include <iostream>
#include <sstream>

std::string input = "abc,def,ghi";
std::istringstream ss(input);
std::string token;

while(std::getline(ss, token, ',')) {
    std::cout << token << '\n';
}

// Tokenizing a string using stringstream 
#include <bits/stdc++.h> 
  
using namespace std; 
  
int main() 
{ 
      
    string line = "GeeksForGeeks is a must try"; 
      
    // Vector of string to save tokens 
    vector <string> tokens; 
      
    // stringstream class check1 
    stringstream check1(line); 
      
    string intermediate; 
      
    // Tokenizing w.r.t. space ' ' 
    while(getline(check1, intermediate, ' ')) 
    { 
        tokens.push_back(intermediate); 
    } 
      
    // Printing the token vector 
    for(int i = 0; i < tokens.size(); i++) 
        cout << tokens[i] << '\n'; 
}
