Convert Boolean Variables to String in Go

In this tutorial, we will learn how to convert Boolean to a string in Go programming language. Boolean is a data type having 1 byte size. It can store any one of the three values mainly True, False or none. String data type is used to store a sequence of characters.

Convert Boolean Variables to String using FormatBool() Functions

Syntax

func FormatBool(b bool) string

This function is present in strconv package. FormatBool() function is used to convert a Boolean variable to string. The function takes the Boolean value as an argument and returns a string.

Algorithm

STEP 1 ? Import the fmt and strconv package.

STEP 2 ? Start the main() function.

STEP 3 ? Initialize a variable of type Boolean and assign a value to it either true or false.

STEP 4 ? Now, call the FormatBool() function present in strconv package by passing the Boolean variable as argument to the function and store the result obtained by this function in a variable.

STEP 5 ? Now, print the result on the screen using fmt.Printf() function.

STEP 6 ? Repeat the steps by changing the value of Boolean variable.

Example

In this program we are writing a go language code to convert Boolean variables to strings using a predefined function called FormatBool().

package main
import (
   "fmt"
   "strconv"
)
func main() {
   var i bool 
   i = false
   string := strconv.FormatBool(i)
   fmt.Printf("Succesfully converted boolean to %T and its value is %v\n", string, string)
   i = true
   string = strconv.FormatBool(i)
   fmt.Printf("Successfully converted boolean to %T and its value is %v\n", string, string)
}

Output

Succesfully converted boolean to string and its value is false
Successfully converted boolean to string and its value is true

Convert a Boolean Variable to String using Sprintf() Function

Syntax

func Sprintf(format string, a ...interface{}) string

This function returns a formatted string. It takes a number of arguments in string format.

The first argument should be a string format followed by a variable number of arguments.

Algorithm

STEP 1 ? Import the fmt package.

STEP 2 ? Start the main() function.

STEP 3 ? Initialize a variable of type Boolean and assign value to it.

STEP 4 ? Call the Sprintf() function by passing the Boolean variable as argument to the function and store the result obtained in a variable called result.

STEP 5 ? Print the final result on the screen using fmt.Println() function.

STEP 6 ? Repeat the above steps by changing the value of Boolean variable and print the result.

Example

In this program we are writing a go language code to convert Boolean variables to strings using a predefined function called FormatBool().

package main
import (
   "fmt"
)
func main() {
   var x bool
   x = true
   string := fmt.Sprintf("%v ", x)
   fmt.Printf("Succesfully converted boolean to %T and its value is %v\n", string, string)
   y := false
   string2 := fmt.Sprintf("%v", y)
   fmt.Printf("Succesfully converted boolean to %T and its value is %v\n", string2, string2)
}

Output

Succesfully converted boolean to string and its value is true 
Succesfully converted boolean to string and its value is false

Conclusion

We have successfully compiled and executed the Golang program to convert a Boolean variable to a string using internal functions along with the examples. In the first example, we used the FormatBool() function present in the strconv package, and in the second one, we used Sprintf() function to achieve the result.
