Golang program to add value to a 64-bit integer in an uninterruptible manner

Here, we are going to learn how to add value to a 64-bit integer in an uninterruptible manner in Golang (Go Language)?

Problem Solution:

Here, we will perform the addition of a number with a 64-bit integer in a synchronized manner. Here, we will use atomic.AddInt64() function. The atomic.AddInt64() function is used in synchronized manner for multithreaded/multi-process environment.

Program/Source Code:

The source code to add value to a 64-bit integer in an uninterruptible manner is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Golang program to add value to a 64-bit
// integer in an uninterruptible manner

package main

import "fmt"
import "sync/atomic"

//Entry point of the program
func main() {
	var num1 int64 = 123457203685477580
	var num2 int64 = -543217203685477580

	res1 := atomic.AddInt64(&num1, 10)
	res2 := atomic.AddInt64(&num2, 20)

	fmt.Println("Result1: ", res1)
	fmt.Println("Result2: ", res2)
}

Output:

Result1:  123457203685477590
Result2:  -543217203685477560

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 required packages to predefined functions.

In the main() function, we created two 64-bit integer variables. Then we added the values to the variables using the atomic.AddInt64() function one by one. After that, we printed the result on the console screen.
