6.20) Write a program that manages a list of up to 10 players and their high scores in the computer's memory. Use two arrays to manage the list. One array should store the players' names, and the other array should store the players' high scores. Use the index of the arrays to correlate the names with the scores. Your program should support the following features: a. Add a new player and score (up to 10 players). b. Print all the players' names and their scores to the screen. c. Allow the user to enter a player's name and output that player's score or a mes- sage if that player's name has not been entered. d. Allow the user to enter a player's name and remove the player from the list. Create a menu system that allows the user to select which option to invoke.

Anew author is in the process of negotiating a contract for a new romance novel. the publisher is offering three options. in the first option, the author is paid $5,000 upon delivery of the final manuscript and $20,000 when the novel is published. in the second option, the author is paid 12.5% of the net price of the novel for each copy of the novel sold. in the third option, the author is paid 10% of the net price for the first 4,000 copies sold, and 14% of the net price for the copies sold over 4,000. the author has some idea about the number of copies that will be sold and would like to have an estimate of the royal- ties generated under each option. write a program that prompts the author to enter the net price of each copy of the novel and the estimated number of copies that will be sold. the program then outputs he royalties under each option and the best option the author could choose. (use appropriate named constants to store the special values such as royalty rates and fixed royalties.
