1. **Run your own program? Say hello to yourself.**
1. Build your program using `go build`
2. And, send it to your friend
(s/he should use be using the same operating system)
(if you're using windows, then hers/his should be
windows too)
3. And then send your program to a friend with a different
operating system.
(So, you should compile your program for her operating system).
**For OSX, type:**
GOOS=darwin GOARCH=386 go build
**For Windows:**
GOOS=windows GOARCH=386 go build
**For Linux:**
GOOS=linux GOARCH=arm GOARM=7 go build
**You can find the full list in here:**
https://golang.org/doc/install/source#environment
2. **Call Print instead of Println** to see what happens.
3. **Call Println or Print with multiple values** by separating them using commas.
4. **Remove double quotes from string literals** and see what happens.
5. **Move the package and import statement** to the bottom of the file and see what happens.
6. **Read Go online documentation**. Take a quick look at the packages and read what they do. Look at their source-code by clicking on their titles.
You don't have to understand anything, just do it. This will warm you up for the upcoming lectures. https://golang.org/pkg
7. Also, **take a tour**: https://tour.golang.org/ See the language features. We're going to talk all about them soon.
