Grabbing a random line seperated by comma's

[viscid hemlock]

My code:
std::string word = "";
std::string letterAmount = "";
std::string descriptionWord = "";
if (file2.is_open()) {

  std::getline(file2, line);
  int commaCount = 0;

  for (int i = 0; i < line.length(); i++) {
    
    std::cout << "line: " << line[i] << std::endl;
    if (line[i] == ',') {
      commaCount++;
    } else {
      if (commaCount == 0) {
        word += line[i];
      } else if (commaCount == 1) {
        letterAmount += line[i];
      } else if (commaCount == 2) {
        if (line[i] != '$') {
          descriptionWord += line[i];
        }
      }
    }
  
    
    
  }

   
  SimonSaysText->label("The " + letterAmount +
                       " letter word I am thinking of is\n " +
                       descriptionWord);

  file2.close();
  std::cout << "2" << line << std::endl;
}

Ok so I have this lab due in a week and I want my code to grab a random line from my file but the lines are like this
Rain,4,Water falling from the sky.$
Book,4,A set of written or printed pages.$
Tree,4,A tall plant with branches and leaves.$
I want my code to grab a random line from one these three using the "descriptionWord" and "letterAmount " as hints for the user so when the user puts their answer in the input box it should match with the "word"

Might be a lot more efficient ways of doing this, but what I'm thinking to grab the random line is to add all the lines to a vector<vector<string>> and that might make it easier

I was able to figure it out but thanks anyway
