Golang program to encode Boolean, integer, and float data using json.Marshal() function

Here, we are going to learn how to encode Boolean, integer, and float data using json.Marshal() function in Golang (Go Language)?
Submitted by Nidhi, on April 16, 2021

Problem Solution:

In this program, we will encode Boolean, Integer, and Floating point numbers using json.Marshal() function.

Program/Source Code:

The source code to encode Boolean, integer, and float data using json.Marshal() function is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Golang program to encode Boolean, integer, and
// float data using json.Marshal() function.

package main

import "fmt"
import "encoding/json"

func main() {
	boolVal, _ := json.Marshal(true)
	fmt.Println(string(boolVal))

	intVal, _ := json.Marshal(25)
	fmt.Println(string(intVal))

	floatVal, _ := json.Marshal(3.14)
	fmt.Println(string(floatVal))
}

Output:

true
25
3.14

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, encoding/json packages then we can use a function related to the fmt and encoding/json package.

In the main() function, we used json.Marshal() function to encode Boolean, Integer, Floating point number. After that, we printed the encoded values using the string() function on the console screen.
