Go language indentation specifications and examples

Indentation specifications and examples of Go language

Go language is a programming language developed by Google. It is characterized by conciseness and clarity. It is famous for its syntax, in which indentation specifications play a vital role in the readability and aesthetics of the code. This article will introduce the indentation specifications of the Go language and explain in detail through specific code examples.

Indentation specification

In the Go language, tabs are used for indentation instead of spaces. Each level of indentation is one tab, usually set to a width of 4 spaces. Such specifications unify coding styles and make teamwork and programming more coordinated.

When writing Go code, you should follow the following indentation specifications:

1. Each code block should have its own indentation level to make the code structure clear.
2. Code within statement blocks should be aligned for easy reading and understanding.
3. The code within the function body should be properly indented so that the logical structure of the function is clearly visible.
4. When nesting at multiple levels, the indentation of each level should be increased by one tab character.

Sample code

The following is a simple Go language sample code that shows the application of indentation specifications:

package main

import "fmt"

func main() {
    for i := 0; i < 5; i++ {
        if i%2 == 0 {
            fmt.Println("偶数：", i)
        } else {
            fmt.Println("奇数：", i)
        }
    }
}

In the above sample code, you can Seeing that proper indentation is used between code blocks makes the entire code structure clear. Code within for loops and if-else statements have been aligned to improve code readability. At the same time, the code inside function main is also indented according to the specifications, making the logical structure of the function clear at a glance.

In short, the indentation specifications of the Go language play an important guiding role when writing code. Following the specifications can improve the readability and maintainability of the code. I hope the content described in this article will be helpful to you when learning and using the Go language.
