Golang program to convert a specified string into Boolean value

Here, we are going to learn how to convert a specified string into Boolean value in Golang (Go Language)?
Submitted by Nidhi, on April 21, 2021

Problem Solution:

Here, we will create a string with some value. After that, we will convert a string value into a Boolean value using strconv.ParseBoolean() function. The strconv.ParseBoolean() function returns two values, first converted Boolean value and another one is err. If the value of err is not nil, it means ParseBoolean() function returns an error.

Program/Source Code:

The source code to convert a specified string into a Boolean value is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Golang program to convert a specified string
// into Boolean value

package main

import "fmt"
import "strconv"

func main() {
	var str string = "true"
	var val bool = false

	//Convert a string into boolean value
	val, err := strconv.ParseBool(str)
	if err != nil {
		panic(err)
	} else {
		fmt.Println("Result: ", val)
	}
}

Output:

Result:  true

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the "fmt", "strconv" packages then we can use a function related to imported packages.

In the main() function, we created a string variable str with "true" value. Then we converted the value of str into Boolean value and assigned it to variable val. After that, we printed the result on the console screen.
