What is a common application of arrays in real-world scenarios?
Step 1: Understand what an array is. An array is a collection of items stored in a single variable.
Step 2: Think about a shopping cart. When you shop online, you can add multiple items to your cart.
Step 3: Realize that each item in the shopping cart can be stored in an array. This means you can keep track of all the items you want to buy.
Step 4: Know that arrays allow you to easily access any item by its position. For example, if you want to see the first item in your cart, you can quickly find it using its index.
Step 5: Conclude that using arrays makes it simple to manage and retrieve items in a shopping cart efficiently.
