Introduction to Arrays
An Array is a fundamental data structure in programming that allows you to store a collection of items, which can be of basic (primitive) types such as numbers, booleans, or strings. Arrays are versatile and can dynamically grow or shrink in size, enabling you to add or remove items as needed. Each item in an array is referred to as an element, and you can access these elements using their index, which starts at 0. This makes arrays a powerful tool for organizing and manipulating data efficiently.
Key Features:
- Dynamic Sizing: Arrays can change in size, allowing for flexible data management.
- Indexing: Access elements using their index for quick retrieval.
- Type Flexibility: Arrays can hold different types of data, including numbers and strings.
Use Cases:
- Storing scores in a game.
- Managing lists of user inputs.
- Organizing data for algorithms that require sequential access.
