## Why `package main` is used in the following program?
|
||||
```go
|
||||
package main
|
||||
|
||||
func main() {
|
||||
}
|
||||
```
|
||||
* It creates a library package
|

* It allows us to properly exit from this program
|

* It creates an executable Go program *CORRECT*

```go
|
||||
package main
|
||||
|
||||
func main() {
|
||||
}
|

```
|

1. It defines a package called main

2. It allows Go to start executing this program by using the code inside func main *CORRECT*
|

## Why `import "fmt"` is used in the following program?
|
||||
```go
|
||||
package main
|
||||
import "fmt"
|
||||
|
||||
func main() {
|
||||
fmt.Println("Hi!")
|
||||
}
|
||||
```
|
||||
1. It prints "fmt" to the console
|
||||
2. It defines a new package called "fmt"
|
||||
3. It imports the `fmt` package; so you can use its functionalities *CORRECT*
|
||||
|
||||
> **1:** `fmt.Println` prints a message not the `import "fmt"`.
|
||||
>
|
||||
>
|
||||
> **2:** `package` keyword does that, not the `import` keyword.
|
||||
>
|
||||
>
|
||||
> **3:** Yes. For example, after you import the fmt package you can call its Println function to print a message to the console.
