Adding value to a 32-bit integer in an uninterruptible manner in Golang

Problem Solution:

Here, we will perform the addition of a number with a 32-bit integer in a synchronized manner. Here we will use atomic.AddInt32() function. The atomic.AddInt32() function is used in synchronized manner for multithreaded/multi-process environment.

Program/Source Code:

The source code to add value to a 32-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 code to add value to a 32-bit integer in an uninterruptible manner

// Golang program to add value to a 32-bit integer
// in an uninterruptible manner

package main

import "fmt"
import "sync/atomic"

// Entry point of the program
func main() {
	var num1 int32 = 67656
	var num2 int32 = -67620

	res1 := atomic.AddInt32(&num1, 10)
	res2 := atomic.AddInt32(&num2, 20)

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

Output:

Result1:  67666
Result2:  -67600

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 32-bit integer variables. Then we added the values to the variables using the atomic.AddInt32() function one by one. After that, we printed the result on the console screen.
