How to use strconv.FormatBool() Function in Golang?

Go language provides inbuilt support to implement conversions to and from string representations of basic data types by strconv Package. This package provides a FormatBool() function which is used to return true or false according to the value of x. To access FormatBool() function you need to import strconv Package in your program with the help of import keyword.

Syntax:

func FormatBool(x bool) string

Parameter: This function takes one parameter of bool type, i.e., x.

Return value: This function returns true or false according to the value of x.

Let us discuss this concept with the help of the given examples:

Example 1:

// Golang program to illustrate
// strconv.FormatBool() Function
package main

import (
    "fmt"
    "strconv"
)

func main() {

    // Finding true or false
    // according to the input value
    // Using FormatBool() function
    fmt.Println(strconv.FormatBool(true))
    fmt.Println(strconv.FormatBool(false))

}

Output:

true
false

Example 2:

// Golang program to illustrate
// strconv.FormatBool() Function

package main

import (
    "fmt"
    "strconv"
)

func main() {

    // Finding true or false
    // according to the input value
    // Using FormatBool() function
    val1 := true
    res1 := strconv.FormatBool(val1)
    fmt.Printf("Result 1: %v", res1)
    fmt.Printf("\nType 1: %T", res1)

    val2 := false
    res2 := strconv.FormatBool(val2)
    fmt.Printf("\nResult 2: %v", res2)
    fmt.Printf("\nType 2: %T", res2)

}

Output:

Result 1: true
Type 1: string
Result 2: false
Type 2: string
