Convert `string` to `int` and vice-versa in Go

Posted on 31 May, 2020

There are basically 2-3 methods to convert integer to string and back to integer but the most easiest way is to use the Itoa and Atoi methods in the strconv package.


package main

import (

func main() {
	// String to Int
	nice, _ := strconv.Atoi("69")
	fmt.Printf("%T", nice)

	//Integer to String
	high := strconv.Itoa(420)
	fmt.Printf("\n%T", high)

Atoi returns a second value (err ignored in this example for easier understanding)

The above code should output:
