I posted this question already but forgot to clarify its in C++

This is the code body I got for python, which does exactly what I need it to do, it just needs to be converted into C++ language.

how to read data from a txt file that looks like this

player1,90,78,82,76,92 player2,67,87,34,90,100 player3,80,81,82,83,84

player4,56,76,98,45,13

player5,89,100,78,100,99

and take the numbers and find the average score for each player and rank their average on a tier scale.

(all scores out of 100)

90 - 100% = S tier

80-89% = A tier

70-79% = B tier

60-69% = D tier

50-59% = F tier

output:

player1 ended with an A tier

(so on so forth)...
