Mastering concurrency can make you a much more in-demand developer on the job market. It's becoming an increasingly important concept in modern programming as multi-core devices become more and more prevalent.

The good news is that Go has some outstanding support for concurrency out of the box that makes implementation a breeze. In fact, concurrency in Go is easier to implement and faster than in any other major language.

In this course, you'll start off with a general introduction to concurrency and build up to more advanced concepts and implementation in Go. You'll also have a chance to go through some common patterns that will make your life easier and your code more efficient. By the time you're done, you'll be able to make use of Go to write efficient, practical applications that use concurrency.

What is the output of the following program?

```Go
func main(){
    var count int
    go func(){
        count++
        fmt.Println(count)
    }()
   go func(){
        count=2
        fmt.Println(count)
 }()
}

  
```

What is the output of the following program?
<pre><code class="language-Go">func main(){
 var count int
 go func(){
 count++
 fmt.Println(count)
 }()
 go func(){
 count=2
 fmt.Println(count)
 }()
}

What is the output of the following program?

```
func main() { 
 channel1 := make(chan string)
 select {
 case <-channel1:
 default:
 fmt.Println("this is the default case.")
 }

```

What is the output of the following program?
<pre><code>func main() {
