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.

Output:
true
false
Example 2:
package main
import (
"fmt"
"strconv"
)
func main() {
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)
