+// EXERCISE: Raw Concat
+//
+//  1. Initialize the name variable
+//     by getting input from the command line
+//
+//  2. Use concatenation operator to concatenate it
+//     with the raw string literal below
+//
+// NOTE
+//  You should concatenate the name variable in the correct
+//  place.
+//
+// EXPECTED OUTPUT
+//  Let's say that you run the program like this:
+//   go run main.go inanç
+//
+//  Then it should output this:
+//   hi inanç!
+//   how are you?
+// ---------------------------------------------------------
+
+func main() {
+	// uncomment the code below
+	// name := "and get the name from the command-line"
+
+	// replace and concatenate the `name` variable
+	// after `hi ` below
+
+	msg := `hi CONCATENATE-NAME-VARIABLE-HERE!
+how are you?`
+
+	fmt.Println(msg)
