What is the function of arrays?

Arrays are used to store multiple values of the same data type in a single variable. They allow for efficient storage and retrieval of data, as well as easy manipulation and processing of large sets of data. Arrays are commonly used in programming to organize and manage data in a structured way, making it easier to work with and analyze large amounts of information.

Arrays are a data structure used in programming to store a collection of elements of the same type. They are often used to represent a list of values, such as a list of numbers or a list of strings.

Arrays are created by specifying the type of element they will store and the number of elements they will contain. Once an array is created, it cannot be resized.

Arrays are accessed using indices, which are numbers that specify the position of an element in the array. The first element in an array has an index of 0, and the last element has an index of length - 1, where length is the number of elements in the array.

Arrays are a convenient way to store and access data in a program. They are often used in loops to process data sequentially.

Here is an example of an array in Python:

```python
numbers = [1, 2, 3, 4, 5]

# Access the first element of the array
first_number = numbers[0]

# Access the last element of the array
last_number = numbers[-1]

# Loop through the array and print each element
for number in numbers:
print(number)
```
