Arrays in Programming

What is an Array?

An array is a data structure that stores a fixed-size sequential collection of elements of the same type. Arrays allow for efficient access to elements using an index.

Key Features of Arrays

• Arrays store elements of the same type, such as integers, strings, or objects.
• Elements are accessed using an index, starting from 0 for the first element.
• Arrays have a fixed size, meaning the number of elements cannot be changed after the array is created.

Common Operations on Arrays

1. Accessing elements using their index, e.g., array[0] for the first element.
2. Modifying elements by assigning a new value to a specific index, e.g., array[2] = 5.
3. Iterating over arrays using loops to process each element.
