Question

(C++) Need simply help with C++ Read File and Sorting program.. Will rate helpful solution thumbs up

Data of 20 user rating on 100 movies is provided. Each row in this data represents the rating of a specific movie and each column represents the user's rating from 1 to 5 for each movie. The title of the movie is shown in the first column and the following columns has the user Id in their 1st row. Develop a program that gets average user ratings for any provided user and additionally find the 5 most popular movies through the dataset. Prompt the user to enter a User Id (available in the 1st row of the dataset) and the average user rating for the selected user will be calculated and shown.
