Step 1: Planning and Designing Your To-Do List

Welcome to our mini-project chapter! This is where we'll take everything we've learned and build something tangible. Our goal is to create a simple command-line To-Do List application. This project will reinforce your understanding of data structures, loops, conditional statements, and user input.

Before we dive into writing any code, it's crucial to plan and design our application. This phase involves thinking about what our To-Do list should do, how it should behave, and what data it needs to manage. A well-thought-out plan will make the coding process much smoother and prevent unnecessary rework.

Let's break down the core functionalities of our To-Do List application:

1. Add a new task: Users should be able to input a new task and have it added to their list.

2. View all tasks: Users should be able to see all the tasks currently in their To-Do list. This includes marking tasks as completed.

3. Mark a task as completed: Users should have a way to indicate that a task has been finished. This might involve displaying it differently or removing it from the active list.

4. Remove a task: Users should be able to delete tasks they no longer need.

5. Exit the application: A way for the user to gracefully close the program.
