Program/Source Code:

The source code to demonstrate the os.Exit() function is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Golang program to demonstrate
// the os.Exit() function

package main

import "fmt"
import "os"

func main() {
	var num int = 0

	fmt.Printf("Enter number: ")
	fmt.Scanf("%d", &num)

	if num > 0 {
		fmt.Printf("Program terminated\n")
		os.Exit(0)
	}
	fmt.Printf("Program finished normally\n")
}

Output:

RUN 1:
Enter number: 3
Program terminated

RUN 2:
Enter number: 0
Program finished normally

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" package to use the Printf() function and we also imported the "os" package to use the Exit() function.

In the main() function, we used os.Exit() function to terminate the execution of the program.
