C++ string split

In the C++, we can split a string with a delimiter as follows.

#include <iostream>
#include <sstream>
#include <string>
#include <vector>


std::vector<std::string> splitString(const std::string &input, char delimiter) {
   std::vector<std::string> res;
   std::stringstream ss(input);
   std::string temp;

   while (getline(ss, temp, delimiter)) {
       res.push_back(temp);
   }
   return res;
}

and we can use the helper function above like this.

auto listOfInputSrc = splitString(request->input.source, ',');

for (const auto &inputSrc : listOfInputSrc) {
    ...
}
