Exercise:
Insert the missing parts to create two types of comments.

[ ....This is a single-line comment
This is a multi-line comment....]

Answer yourself in the comments🌸

Single-line Comments
Single-line comments start with two forward slashes (//).

Any text between // and the end of the line is ignored by C # (will not be executed).

This example uses a single-line comment before a line of code:

Example:
// This is a comment
Console.WriteLine("Hello World!");

This example uses a single-line comment at the end of a line of code:

Example:
Console.WriteLine("Hello World!");

C # Multi-line Comments
Multi-line comments start with /* and ends with */.

Any text between /* and */ will be ignored by C #.

This example uses a multi-line comment (a comment block) to explain the code:

Example
/* The code below will print the words Hello World
to the screen, and it is amazing */
Console.WriteLine("Hello World!");

Single or multi-line comments?
It is up to you which you want to use. Normally, we use // for short comments, and /* */ for longer.

Example Get your own C # Server
Console.WriteLine("Hello World!");

You can add as many WriteLine() methods as you want. Note that it will add a new line for each method:

C # Syntax
In the previous chapter, we created a C # file called Program.cs, and we used the following code to print "Hello World" to the screen:

Example explained
Line 1: using System means that we can use classes from the System namespace.

Line 2: A blank line. C # ignores white space. However, multiple lines makes the code more readable.

Line 3: namespace is used to organize your code, and it is a container for classes and other namespaces.

Line 4: The curly braces {} marks the beginning and the end of a block of code.

Line 5: class is a container for data and methods, which brings functionality to your program. Every line of code that runs in C # must be inside a class. In our example, we named the class Program.

Don't worry if you don't understand how using System, namespace and class works. Just think of it as something that (almost) always appears in your program, and that you will learn more about them in a later chapter.

Line 7: Another thing that always appear in a C # program is the Main method. Any code inside its curly brackets {} will be executed. You don't have to understand the keywords before and after Main. You will get to know them bit by bit while reading this tutorial.

Line 9: Console is a class of the System namespace, which has a WriteLine() method that is used to output/print text. In our example, it will output "Hello World!".

If you omit the using System line, you would have to write System.Console.WriteLine() to print/output text.

Note: Every C # statement ends with a semicolon ;.

Note: C # is case-sensitive; "MyClass" and "myclass" have different meaning.

Note: Unlike Java, the name of the C # file does not have to match the class name, but they often do (for better organization). When saving the file, save it using a proper name and add ".cs" to the end of the filename. To run the example above on your computer, make sure that C # is properly installed: Go to the Get Started Chapter for how to install C #. The output should be:

C # IDE
The easiest way to get started with C # is to use an IDE.

An IDE (Integrated Development Environment) is used to edit and compile code.

Applications written in C # use the .NET Framework, so it makes sense to use Visual Studio, as the program, the framework, and the language, are all created by Microsoft.
•C # Install
Once the Visual Studio Installer is downloaded and installed, choose the .NET workload and click on the Modify/Install button:

•After the installation is complete, click on the Launch button to get started with Visual Studio.

On the start window, choose Create a new project:

•Then click on the "Install more tools and features" link:

•Choose "Console App (.NET Core)" from the list and click on the Next button:

•Enter a name for your project, and click on the Create button:

•Visual Studio will automatically generate some code for your project:

What is C #?
C # is pronounced "C-Sharp".

It is an object-oriented programming language created by Microsoft that runs on the .NET Framework.

C # has roots from the C family, and the language is close to other popular languages like C++ and Java.

The first version was released in year 2002. The latest version, C # 12, was released in November 2023.

C # is used for:

Mobile applications
Desktop applications
Web applications
Web services
Web sites
Games
VR
Database applications
And much, much more!
Why Use C #?
It is one of the most popular programming languages in the world
It is easy to learn and simple to use
It has huge community support
C # is an object-oriented language which gives a clear structure to programs and allows code to be reused, lowering development costs
As C # is close to C, C++ and Java, it makes it easy for programmers to switch to C # or vice versađź’š

Tips For Teaching Kids How to Code:
Coding can be a fun and interactive experience for you and your child. Whether you’re sitting down and working with your child or allowing them to explore the world of programming while you get work done, here are some tips to keep in mind as they engage on the computer.

Challenge Kids Ideas of Computers

Start off the conversation by asking, “What is a computer?”. Then have a couple of pictures of household items that include different types of computers or technology like a self-flushing toilet, sprinklers, or even pets.
Ask your kids to identify which of the photos are computers. When they look baffled, explain that all of these examples are computers. For example, the toilet has sensors that detect motion and communicate for the device to flush and sprinklers are set on a timer to go off on certain days at certain times.
Even pets can be considered a computer if they have microchips in their skin that store home addresses and contact information. By using examples they understand, parents can make computers and technology seem more interesting and something they can engage with daily.

These exercises challenge the perception that computers are just rectangular boxes with screens. With today’s technology and the emerging Internet of Things (IoT), anything can be a computer! Being on the computer can be a fun, educational, and immersive experience for a child as they learn how to focus, analyze, and train their brain with a new skill. Change up their routine using these amazing resources that can keep them entertained for hours.
