Specified format example for converting a Boolean value to a string
In the Go language, you can use thestrconv.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 useFormatBool()
Another variant of the functionFormatBool(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 thestrconv.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 thestrconv.FormatBool()
function to convert the Boolean valuestatus
to a string, and output it using the default format and custom format respectively.
By default, thestrconv.FormatBool()
function will converttrue
to the string"true"
andfalse
Convert to string"false"
. Different formats can be set in custom functions as needed.
In theformatBool()
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 thestrconv.FormatBool()
function, making our code more concise and readable.
