How to wrap lines in golang (multiple methods)

In Golang, line wrapping is a common operation and can be achieved using \n characters.

In Golang, \n is a special character that represents a newline. When \n is encountered, the program will move the cursor to the beginning of the next line. Newline characters can be used in strings and in output statements.

The following are several usage examples of newlines:

1. Newline characters in strings:

In Golang, you can use double quotes or backticks to create characters string. Within double quotes, you can use \n to represent a newline character. For example:

str := "第一行\n第二行\n第三行"
fmt.Println(str)

The output result is:

第一行
第二行
第三行

2. The newline character in the output statement

In the output statement, you can use \n to change the line. For example:

fmt.Println("第一行")
fmt.Println("第二行")
fmt.Println("第三行")

The output result is also:

第一行
第二行
第三行

3. Use the Println function

In Golang, the Println function will automatically add a newline character at the end of the output statement. For example:

fmt.Println("第一行")
fmt.Println("第二行")
fmt.Println("第三行")

The output result is also:

第一行
第二行
第三行

Summary

There are many ways to wrap lines in Golang. You can use the \n character. Line breaks in the string can also be achieved by using \n in the output statement. In addition, the Println function in Golang will automatically wrap lines to facilitate developers' output. Either way, the newline operation in Golang can be implemented well.
