Introduction: In the previous post , we explored control structures in C#, including if/else statements, switch statements, and various looping constructs (for, while, and do/while). In this post, we'll delve into arrays and collections, which are essential data structures for storing and manipulating groups of related data items. After this article, we'll move on to the next chapter: "Object-Oriented Programming with C#." Arrays: An array is a fixed-size, ordered collection of elements of the same data type. The elements in an array can be accessed by their index, which starts from zero. Creating and Initializing Arrays: There are multiple ways to create and initialize arrays in C#. Here are some common examples: Declare an array with a specified size: int [] numbers = new int [5]; Declare and initialize an array with specific values: int [] numbers = { 1, 2, 3, 4, 5 }; ...
