export variable

[sourav977]

you are calling in main file like: fmt.Println(helloworld())
in test file also you are calling like helloworld()

it will fail.
as helloworld function is not exported. Test file will unable to call because it is not exported.
in both file, call as Helloworld().

I thought the same thing. So I forked this repo, downloaded it locally, relearned golang, installed golang 1.11.1 then build the project and ran the tests.
And here's what I got.

~/go/src/github.com/LarryBattle/helloworld (master)$ go run main.go
Hello World!!

~/go/src/github.com/LarryBattle/helloworld (master)$ go test -cover
PASS
coverage: 50.0% of statements
ok      github.com/LarryBattle/helloworld       0.185s

I just wasted my time.

Why export the variable?
