Question

PLEASE DO IT IN THE SIMPLE WAY AND TRY DON'T DO WITH THE VECTOR AS IT COMPLICATE TO UNDERSTAND THE CODE.

This is a C++ question, in this question you need to create HightScoreManager and User class.

HighScoreManager class should have a function to create a record and save it to a file organized descending based on the score and to print the top 10 High Scores to the screen. The class should look like the following. The High score structure should be stored in a binary file called highScore.dat file.

Class HighScoreManager

Private: Structure (username, score, date)

Public: CreateHighScore, UpdateHighScore, PrintHighScore

The user class will have the user login with his username if the username does not exist it will be added to a list of records. Once logged in the user will be able to update his info, set a high score, delete his information, or print all the high scores in a table format. The users will be stored in a text file called user.txt

The user class will contain the following:

Class User

Private: Structure (username, user info(between 1-4 fields)

Public: Login, CheckIfUserExist, UpdateUserList, DeleteUser, SetHighScore

In the main, the user will first login and then be shown a menu with the options to update his info, set a high score, delete his information, print all the high scores, exit.
