Convert an integer to string using strconv.Itoa() function in Golang

Problem Solution:

Here, we will create an integer number with some initial value and then we will convert it into a numeric string using strconv.Itoa() function.

Program/Source Code:

The source code to convert a specified integer number to a numeric string using strconv.Itoa() function is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

Golang code to convert an integer to string using strconv.Itoa() function

// Golang program to convert a specified integer number to
// a numeric string using strconv.Itoa() function

package main

import "fmt"
import "strconv"

func main() {
	var num int = -203

	//Convert an integer number to a numeric string.
	str := strconv.Itoa(num)

	fmt.Println("Numeric string: ", str)
}

Output:

Numeric string:  -203

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 an integer variable num initialized with -203. Then we converted the integer number into a numeric string using strconv.Itoa() function. After that, we printed the result on the console screen.
