C++ file input question:-

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){ }

File:
