Welcome back! In the previous lessons, we discussed connecting to Redis and performing operations with numbers using C++. Now, let's explore another essential Redis data structure: lists. Lists in Redis are an excellent way to store ordered collections of items, such as names, messages, or even tasks.

By the end of this lesson, you'll know how to:

1. Use the RPUSH command to add items to a Redis list.
2. Retrieve list items using the LRANGE command.

Here's a quick look at how you'll be working with lists in Redis using C++:

In this example:

• The RPUSH command adds the names Alice, Bob, and Charlie to the list named students. The first argument is the list name, followed by the items to add.
  • Note that since Redis is a key-value store, if you run the same code multiple times, the list will keep growing with the same elements, as lists in Redis allow duplicates.

Working with lists in Redis is fundamental for various real-world applications. For instance, if you're developing a messaging application, lists can help manage message queues efficiently. They can also be used for task management systems, where tasks are added, processed, and completed in a specific order.

Lists offer an intuitive and powerful way to handle data sequences. By mastering lists in Redis, you'll enhance your ability to manage ordered collections of data, making your applications more robust and efficient.
