Question

I WILL GIVE FULL RATING
Write a short user login code in C++.
Please follow these guidelines:-
This should be simple. There should be a text file that containsuser names and their passwords. In the program, a message (onscreen) is displayed asking for user login name and password. Thepassword should be hidden, by *s as normal. If a user wants tologin, then the program can check if such user name exists (fromtextfile) or if there is such a user name, then check if thepassword is correct (by comparison). If no such user name existsthen a message e..g. "you are not relevant user" should appear. Ifuser login is correct but password is incorrect, then "wrongpassword" message should appear. I think that simple user logincode does not need "forgot password" option, so include it if youcan, else ignore it. If all is correct, then message "you havelogged in successfully" should be displayed. Then a message "if youwant to log out enter O" and if user enter "O", the message "youhave logged out sucessfully" appears, and the program ends.
