Demystifying Golang escape symbols: improving code stability

Go language is a programming language that is efficient, easy to learn and use, and it involves the use of escape symbols when processing strings. An escape character is a special character that tells the compiler how to interpret the following characters.

In the Go language, we often encounter situations where we need to use escape symbols, such as inserting special characters into strings, expressing newlines, etc. Correct use of escape symbols can not only make the code clearer and easier to understand, but also improve the stability and maintainability of the code.

The following will introduce some commonly used escape symbols and how to use them, and use specific code examples to help everyone better understand and apply escape symbols.

1. The newline character `

`

`
is a common escape symbol used to represent a newline. When we need to achieve a newline effect in a string, we can use
` to express it.

package main

import "fmt"

func main() {
    fmt.Println("第一行
第二行")
}

Copy after login

The above code will output:

第一行
第二行

Copy after login

2. Double quotes"

Double quotes" in Go language Used to indicate the start and end of a string. If you need to include double quotes in the string, you need to use the escape symbol ".

package main

import "fmt"

func main() {
    fmt.Println("He said: "Hello!"")
}

Copy after login

The output result is:

He said: "Hello!"

Copy after login

3. Backslash\

In Go language, backslash` is the starting symbol for escape symbols. If you need to include backslash in the string Slash can be represented by \`.

package main

import "fmt"

func main() {
    fmt.Println("C:\Users\Desktop")
}

Copy after login

The output result is:

C:UsersDesktop

Copy after login

4. Tab character

Tab Character is used to insert horizontal tab characters in strings, usually used for typesetting output.

package main

import "fmt"

func main() {
    fmt.Println("姓名    年龄    职业")
    fmt.Println("张三    25    工程师")
}

Copy after login

The output result is:

姓名    年龄    职业
张三    25    工程师

Copy after login

5. Carriage return character``

The carriage return character` is used to move the cursor to the beginning of the current line, and is often used in conjunction with the line feed character
` to achieve the effect of re-output.

package main

import "fmt"

func main() {
    fmt.Println("Loading...Complete!")
}

Copy after login

The output result is:

Complete!

Copy after login

The above are some commonly used escape symbols and how to use them. I hope that these code examples can help everyone better understand and master the use of escape symbols in the Go language. Use escapes appropriately. Symbols can make the code clearer and easier to understand, improve the stability and maintainability of the code, and make our programming work more efficient and elegant.
