Right now, we have a player named Alex who scored 75 points! Our goal is to move some of this logic into functions. Pretty simple, right? In this exercise, we want to write our code in a top-down fashion, which means we will start by modifying the main function to use functions that we haven't implemented yet. This approach allows us to focus on how we want to use the functions before we worry about how they are implemented. So, let's look at the main function. We want to refactor this code by using three functions. One, to get the player's name, one to calculate the player's score, and one to display the score. First, let's modify the main function to use these functions as if they were already written. We'll start at line nine by calling a function named getplayerName to retrieve the player's name.
