Use the strconv.FormatBool function to convert a Boolean value to a string and set it to the specified format

Specified format example for converting a Boolean value to a string

In the Go language, you can use the strconv.FormatBool() function to convert a Boolean value to a string. This function accepts a Boolean value as a parameter and returns the Boolean value as a string.

To set the string format after Boolean value conversion, you can use FormatBool()Another variant of the function FormatBool(v bool) string. This variant function converts a Boolean value to a string and then formats it according to the specified format.

The following is an example of using the strconv.FormatBool() function to convert a Boolean value to a string and set it to the specified format:

package main

import (
    "fmt"
    "strconv"
)

func main() {
    status := true
    str := strconv.FormatBool(status)
    fmt.Println("Default Format:", str)

    str = strconv.FormatBool(status)
    fmt.Println("Custom Format:", formatBool(str, "Y", "N"))
}

func formatBool(str string, formatTrue string, formatFalse string) string {
    if str == "true" {
        return formatTrue
    } else if str == "false" {
        return formatFalse
    }
    return ""
}

In the above example , we use the strconv.FormatBool() function to convert the Boolean value status to a string, and output it using the default format and custom format respectively.

By default, the strconv.FormatBool() function will convert true to the string "true" and false Convert to string "false". Different formats can be set in custom functions as needed.

In the formatBool() custom function, we format the "true" string into "Y" and "false"The string is formatted as "N". If the incoming string is neither "true" nor "false", an empty string is returned.

The output is as follows:

Default Format: true
Custom Format: Y

Through this example, we can see how to convert a Boolean value to a string and format it differently as needed. This function can be easily implemented using the strconv.FormatBool() function, making our code more concise and readable.
