Append CSV file in C++

  append, c++, csv

is there a way in which I can update a specific record in my csv file? In my problem, the user chooses a website from a set of websites. Each website has a score which increases when chosen. My csv file has a list of all websites and their scores, I want to update the score of the chosen website without reading all the data and writing it again.
