How to escape characters in golang

In programming, we often need to use special characters in strings, such as newlines, tabs, quotation marks, etc. In order to avoid problems with these special characters in writing, we need to escape them. In Go language, we can use escape characters to achieve this function.

Escape characters are special symbols that start with a backslash (\) and are followed by one or more characters. These symbols tell the compiler that these characters in the string should be replaced by special characters. The following are the commonly used escape characters in Go language and their corresponding character meanings:

• \n: represents the newline character
• \t: Represents tab character
• \": Represents quotation mark
• \': Represents single quotation mark

• \\: Represents backslash

  For example, if we need to use quotation marks in a string, we need to use backslash to escape. For example:

package main

import "fmt"

func main() {
    str := "\"Hello, world!\""
    fmt.Println(str)
}

The output result is: "Hello, world!"

If we need to use newline characters in the string, we need to use \nEscape. For example:

package main

import "fmt"

func main() {
    str := "Hello\nworld!"
    fmt.Println(str)
}

The output result is:

Hello
world!

When performing database queries, we often need to use single quotes (') to enclose strings. At this time, if The string itself also contains single quotes, which need to be escaped using \. For example:

package main

import "fmt"

func main() {
    str := "Don\'t worry, be happy!"
    fmt.Println(str)
}

The output result is: Don't worry, be happy!

The use of escape characters in the Go language to handle special characters helps us write standardized code. However, excessive use of escape characters can also lead to reduced code readability. Therefore, in actual programming, we should Use escape characters reasonably according to the actual situation.

In summary, using escape characters in Go language can handle special characters in strings, make the code more standardized, and improve the readability and Maintainability. Being proficient in escape characters makes it easier for us to write high-quality code.
