How can I read a text lien by line and separate the text it by comma

#include <fstream>
#include <sstream>
#include <string>

int main()
{
    // Open file
    std::ifstream infile("D:\\accounts.txt");

    // read line by line
    std::string line;
    while (std::getline(infile, line))
    {
        std::istringstream iss(line);

        std::string username;
        std::string password;

        // read username and password from each line
        std::getline(iss, username, ',');
        std::getline(iss, password, ',');

        // use username/password further...
    }

	return 0;
}

</string></sstream></fstream>
