Go Sample Example - WaitGroup with Anonymous Functions

This repository demonstrates how to use a Go WaitGroup in conjunction with anonymous functions to synchronize multiple goroutines. It showcases how to launch goroutines with anonymous functions and wait for their completion using a sync.WaitGroup.

📖 Information

• This example demonstrates the use of WaitGroups with anonymous functions in Go.
• It covers launching multiple goroutines, each using an anonymous function to simulate a task, and synchronizing their completion using a `sync.WaitGroup`.
• The example shows how to pass arguments to anonymous functions within goroutines.

💻 Code Example

package main

import (
	"fmt"
	"sync"
)

func main() {

	// WaitGroup with Anonymous Functions
	// Demonstrates using a WaitGroup with an anonymous function

	var wg sync.WaitGroup
	n := 5

	for i := 1; i <= n; i++ {
		wg.Add(1)
		go func(id int) {
			defer wg.Done()
			fmt.Printf("Worker %d is processing\n", id)
		}(i)
	}

	// Wait for all workers to finish
	wg.Wait()
	fmt.Println("All workers completed.")
}

🏃 How to Run

1. Make sure you have Go installed. If not, you can download it from here.
2. Clone this repository:

git clone https://github.com/Rapter1990/go_sample_examples.git

3. Navigate to the 023_waitgroup directory:

cd go_sample_examples/023_waitgroup/002_waitGroup_with_anonymous_functions

4. Run the Go program:

go run 002_waitGroup_with_anonymous_functions.go

📦 Output

When you run the program, you should see the following output:

Worker 3 is processing
Worker 2 is processing
Worker 5 is processing
Worker 4 is processing
Worker 1 is processing
All workers completed.
