Can you explain what is meant by the concept of an array in programming?

An array in programming is a data structure that stores a fixed number of elements of the same type in contiguous memory locations.

Main characteristics of an array:

• Elements are indexed by integers, usually starting from 0.
• Access to elements is done in constant time (O(1)).
• The size of the array is fixed upon creation and does not change.

Example of an array in C#:

int[] numbers = new int[3];
numbers[0] = 10;
numbers[1] = 20;
numbers[2] = 30;

Console.WriteLine(numbers[1]); // Outputs 20

Arrays are convenient for storing and quickly accessing a set of homogeneous data.
