Exit

The problem to be solved in this challenge is to exit a Go program with a specific status code using the os.Exit function.

Requirements

To complete this challenge, you will need to have a basic understanding of Go programming and the os package.

Example

##  If you run `exit.go` using `go run`, the exit
## will be picked up by `go` and printed.
$ go run exit.go
exit status 3

## By building and executing a binary you can see
## the status in the terminal.
$ go build exit.go
$ ./exit
$ echo $?
3

## Note that the `!` from our program never got printed.

Summary

In this challenge, you learned how to use the os.Exit function to immediately exit a Go program with a specific status code. Remember that unlike other programming languages, Go does not use an integer return value from main to indicate exit status.
