	"time"

func main() {
	// 3. Declare variables
	var myVar int = 42
	myVar2 := 10
	
	// 4. Functions
	result := add(myVar, myVar2)
	fmt.Println("Sum:", result)

	// 5. Control structures
	if result > 50 {
		fmt.Println("Greater than 50")
	} else {
		fmt.Println("Not greater than 50")
	}

	// 6. Import packages & 7. Goroutines and channels
	c := make(chan string)
	go printHello(c)
	msg := <-c
	fmt.Println(msg)
}

// Function example
func add(x int, y int) int {
	return x + y
}

// Goroutine example
func printHello(c chan string) {
	time.Sleep(1 * time.Second)
	c <- "Hello, from goroutine!"
