Title: Methods and examples of formatted output using Go language

Go language is a concise and efficient programming language. When outputting, we usually The output needs to be formatted to make it more readable. This article will introduce how to use Go language for formatted output, including commonly used formatting verbs and sample codes.

Formatting verb

In the Go language, formatted output is achieved by using the Printf function in the fmt package. In the Printf function, we can use different formatting verbs to format the output. Some of the commonly used formatting verbs include:

• %d: Represents an integer
• %f: Represents a floating point number
• %s: Represents a string
• %v : Indicates the general format

In addition to the above formatting verbs, there are other formatting verbs that can meet more complex output requirements. Readers can choose the appropriate formatting verb according to the actual situation.

Sample Code

Here is some sample code that demonstrates how to format the output using different formatting verbs:

package main

import "fmt"

func main() {
    // Integer formatting
    num := 10
    fmt.Printf("Integer: %d
", num)

    //Floating point number formatting
    pi := 3.1415926
    fmt.Printf("Floating point number: %f
", pi)

    // String formatting
    name := "Alice"
    fmt.Printf("String: %s
", name)

    //general formatting
    age := 20
    height := 175.5
    fmt.Printf("Age: %v, Height: %v
", age, height)
}

In the above sample code, we used %d, %f, %s and %v## respectively. #Format verbs output in integers, floating point numbers, strings and general formats. Readers can run the above code and observe the output effects of different types of data under different formatting verbs.

Through the above sample code, readers can learn how to use Go language for formatted output, and select appropriate formatting verbs for output according to actual needs. Formatted output can make the output results clearer and easier to read, and improve the readability and maintainability of the code.
