- Write a Go program that keeps reading integers until you give the number 0 as input, then it prints the minimum and maximum integer in the input.
- Write the same Go program as before, but this time, you will get your input using command-line arguments. Which version do you think is better? Why?
- Write a Go program that supports two command-line options (-i and -k) in random order using if statements. Now change your program to support three command-line arguments. As you will see, the complexity of the latter program is just too much to handle using if statements.
- If the indices of a map were natural numbers, are there any cases that it would be wise and efficient to use a map instead of an array?
- Try to put the functionality of array2map.go into a separate function.
- Try to develop your own random number generator...

Go Systems Programming
Overview of this book
Go is the new systems programming language for Linux and Unix systems. It is also the language in which some of the most prominent cloud-level systems have been written, such as Docker. Where C programmers used to rule, Go programmers are in demand to write highly optimized systems programming code.
Created by some of the original designers of C and Unix, Go expands the systems programmers toolkit and adds a mature, clear programming language. Traditional system applications become easier to write since pointers are not relevant and garbage collection has taken away the most problematic area for low-level systems code: memory management.
This book opens up the world of high-performance Unix system applications to the beginning Go programmer. It does not get stuck on single systems or even system types, but tries to expand the original teachings from Unix system level programming to all types of servers, the cloud, and the web.
