Arrays are an important part of any programming language as they let us group together and manipulate a large amount of similar data. In this section we will learn about Arrays and how to use them for practical applications.

6. Methods

In this section we will learn about one of of the most widely used and essential features of C# called Methods. We will also explore its uses through creative practice tasks.

Comments

In programming, comments are parts of code that are meant for leaving messages, notes or perhaps comments, in the code, for yourself or for other people who might read it. A comment does not affect the functionality of the program.

A Single-Line Comment can be added using the double forward slash (//) operator:

main.cs

A Multi-Line Comment can be added by enclosing the text inside /* and */ operators.

main.cs

Multi-Line comments can also be used to comment out parts of a single line. For-example:

main.cs

It is also a common practice to comment-out a piece of code which we temporarily want to exclude from the program:

main.cs

What lines will be included in the output of the following program?
