Real Life Examples of Using Arrays and Lists in Software Development

📚 Quick Study Guide

• 🔑 Arrays: Fixed-size, indexed collections of elements of the same data type. Access elements using their index (e.g., `array[0]`).
• 📝 Lists: Dynamic-size, ordered collections of elements. Offer methods for adding, removing, and inserting elements.
• ⏱️ Arrays vs. Lists: Arrays are generally faster for accessing elements by index. Lists are more flexible for adding/removing elements.
• 🧮 Common Operations: Both support iteration (looping through elements), searching, and sorting.
• 🧠 Use Cases: Arrays for fixed-size data (e.g., pixel data in an image). Lists for collections that change size frequently (e.g., a to-do list).
