Summary

You learned many things in this chapter, including getting user input and processing command-line arguments. You familiarized yourself with the basic Go structures and you created a Go program that generates random numbers. Try to do the offered exercises and do not get discouraged if you fail in some of them.

The next chapter will talk about many advanced Go features, including error handling, pattern matching, regular expressions, reflection, unsafe code, calling C code from Go, and the strace(1) command-line utility. I will compare Go with other programming languages and give you practical advice in order to avoid some common Go pitfalls.
