Reading data from csv file C++ - c++

Question

Hi my project have many csv files. Which is located in the same directory as Datafolder/IAG/day1.csv, Datafolder/IAG/day2.csv and Datafolder/IAG/day3.csv. Same for Datafolder/CBA/day1.csv, Datafolder/CBA/day2.csv and Datafolder/CBA/day3.csv and Datafolder/NAB/day1.csv, Datafolder/NAB/day2.csv and Datafolder/NAB/day3.csv.
my goal is user can input which day's data they want and input. Once they input it will ask the user to enter either 1(to get the highest price value) or 2(lowest price value). But in my code I dont why once the user select the day and get the highest price it is stored as that value. Even though the user select another day and look for the highest price it is not actually displaying that day's highest value but the previous day's highest value which copied over again The following is codes. Thanks in advance guys.
