Can you explain what a data structure consisting of sequential elements of the same type is?

A data structure consisting of sequential elements of the same type is called an array.

Arrays allow storing a fixed number of elements of the same type, providing quick access by index.

Example of an array in C#:

int[] numbers = new int[5];
numbers[0] = 10;
numbers[1] = 20;
// and so on

Here, numbers is an array of 5 integers, with elements indexed from 0 to 4.
