Another common way to comment code is by using multi-line comments. Multi-line comments allow you to comment out multiple lines or blocks of code. In many programming languages, multi-line comments start with a forward slash and asterisk (/*) and end with an asterisk and forward slash (*/). Here’s an example:

“`java
/* This is a multi-line comment in Java
You can comment out multiple lines or blocks of code
by enclosing them within the comment symbol.
For example, let’s comment out the following code: */

// System.out.println(“This code won’t execute!”);

System.out.println(“This code will execute!”);
“`

By using multi-line comments, you can temporarily disable blocks of code without having to remove them from your source file. This can be useful when debugging or testing different parts of your code.

Visual Studio Code also provides the option to toggle comments on selected lines. This feature allows you to quickly comment or uncomment multiple lines of code simultaneously. By default, the shortcut key for toggling comments is `Ctrl+/` on Windows and Linux, and `Cmd+/` on macOS. Alternatively, you can right-click on the selected lines and choose the “Toggle Line Comment” option from the context menu.

In addition to single-line and multi-line comments, Visual Studio Code supports a special form of comment called “documentation comments” or “doc comments”. Doc comments are primarily used to generate documentation for your code. They typically follow a specific format, often defined by the programming language or a documentation generator. For example, in Java, doc comments start with a forward slash and two asterisks (/**) and end with an asterisk and forward slash (*/). Visual Studio Code recognizes doc comments and provides helpful features like syntax highlighting and auto-completion.

Now, let’s address some frequently asked questions about commenting in Visual Studio Code:

Q1: How can I quickly add a block of comments to my code?
A1: One way to achieve this is by selecting the block of code and using the toggle comment feature (`Ctrl+/` or `Cmd+/`). This will add the necessary comment symbols at the beginning of each line.
