Golang program to convert a specified numeric string into integer using strconv.Atoi() function

Program/Source Code:

The source code to convert a specified numeric string into an integer using strconv.Atoi() function 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
// an integer using strconv.Atoi() function

package main

import "fmt"
import "strconv"

func main() {
	var str string = "-203"
	num, err := strconv.Atoi(str)

	if err != nil {
		panic(err)
	} else {
		fmt.Println("Num: ", num)
	}
}

Output:

Num:  -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 a str variable initialized with "-203". Then we converted the numeric string into an integer number strconv.Atoi() function. After that, we printed the result on the console screen.
