C++ file input question:-

Note : I had posted the same question a little while ago (you can see it here https://www.chegg.com/homework-help/questions-and-answers/c-file-input-question-want-input-file-format-pasted--preferable-use-instream-loops-getline-q44093432?trackid=cMeCMorG) but the only problem was the number of lines between each event can vary depending on the file we read in. Meaning that we may have more than three athletes in a different file we have to read in.

I want to input a file that is in the format pasted below. It is preferable to use instream and a while loops such as, getLine is the last option. How do I input this in a way where I can get data for each event separately (because later they need to be calculated in different ways):

CODE (I don't know how to do it exactly but I know we have to do it in a way similar to this):

std::ifstream in_str();

if (!in_str.good()) { std::cerr << "Can't open " << argv[3] << " to read. "; exit(1); }

if(in_str >> event >> event_name ){

}

while(in_str >> first_name >> last_name >> country >> score){ }
