why fmt.Println?

I used the Println function of the fmt package , which is similar to the stdio in C. I could have used simple Print or Printf function too. But just that Println adds a new line at the end of the output.

that's right but why we would require a new line at the end of output here?

We actually don't. I just gave it as in C++ we mostly add endl to cout as a practice, so did the same here too. Should I change the function to just Print then?

don't mix c++ syntax with golang initially it happens but try not to. And always it what the program requires not on the language. Here, we don't want to a new line after Hello World right? So, don't use Println use Print instead.
I know these are small things but we have to think about these too. 🙂
