Hello Looking for some help to solve a problem I can't figure out. For example I'm given a command ('D') to remove a player (Lastname: Green, Firstname: Tommy) from the players list. I'm given class and functions I must use in the program and they're all in my program. I am not allowed to use any more private/public fields or methods in the four classes I'm given. Except I can use private methods in the Tournament class. variables have to be local. I know i have to create a find player function in the Tournamnet class in the private are, but I can't figure out how to compare the player last and first name the methods I'm given. I have a method that read players state, point, last, and first names. Thu when I have to remove a player. Im only given their last and first name. I feel I have to take the cin last and first name and use GetLastName() and GetFirstName(), and compare them to the cin last and first name. That's where Im at now. Any help with examples or explanations would be great. Thank you.
