Int to string

To convert int to string in Golang you can use one of the following methods:

  • strconv.FormatInt: FormatInt returns the string representation of i in the given base, for 2 <= base <= 36. The result uses the lower-case letters 'a' to 'z' for digit values >= 10.
  • strconv.Itoa: Itoa is shorthand for FormatInt(int64(i), 10)
package main

import (
	"fmt"
	"strconv"
)

func main() {

	i1 := 1234

	/** converting the i1 variable into a string using Itoa method */
	str1 := strconv.Itoa(i1)
	fmt.Println(str1)

	i2 := 5678
	/** converting the i2 variable into a string using FormatInt method */
	str2 := strconv.FormatInt(int64(i2), 10)
	fmt.Println(str2)
}

Compile&Run

To compile the code navigate to the file location and run the following command.

$ go build int_to_string.go

Then depending if you are on Linux or windows the binary file is created.

To run the application execute the command.

Linux

$ int_to_string

Windows

c:\Users\adm\go\tutorials> int_to_string.exe

If you want to compile and run the application in one single step run the following command:

go run int_to_string.go

Output

will display the int numbers in string format.
