How to write multi-line comments in golang

In programming, comments are a very important task. It can help programmers better understand their own code, and can also give others a clear and easy-to-understand code reading experience. In the Golang programming language, using multi-line comments is a common practice. This article will introduce how to use multi-line comments in golang, as well as some considerations for them.

1. What is a multi-line comment?
In golang programming, the syntax format of a multi-line comment is as follows:
/*
Here is the content of the multi-line comment
*/
Multi-line comments start with / and end with /. You can enter any content in the middle, including code and explanations, etc.

2. Common application scenarios of multilines in golang
1. For a relatively long code segment, when you want to temporarily exclude its role in the program, use multi-line comments to effectively hide it. No need to Comment or delete them all, leaving only one or a few.

2. Write comments. Multi-line comments can not only be used to hide code, but can also be used to add comments during program design and development, such as adding function descriptions, parameter descriptions, return value descriptions, usage examples, etc., to facilitate developers' later use and reading.

3. Precautions for using multilines in golang
1. Multiline comments cannot be nested in golang, that is to say, you cannot add a multiline comment to a multiline comment.

2. In a golang source code file, multi-line comments can appear in front of package and import. These comments can be parsed by the documentation tool in godoc and added to the result page.

3. When encountering multiple multi-line comments, each multi-line comment must be written in a separate / ... / block, and the comment information cannot be connected together.

4. Suggestion: Single-line comments explain variables, functions, conditions, loops, etc. in the code; multi-line comments add functional descriptions after completing important functional requirements to elaborate on the function, input, and Details such as output, input validation, and error handling make the code more readable.

4. Summary
In the process of writing code in golang, multi-line comments are a very practical technique. You can hide code and add comments to improve code readability and maintainability. However, you must pay attention to the format and usage specifications of multi-line comments to avoid unnecessary errors and confusion.
