Hands-On Go Programming

By: Tarik Guney

Overview of this book

<p>With its C-like speed, simplicity, and power for a growing number of system-level programming domains, Go has become increasingly popular among programmers. Hands-On Go Programming teaches you the Go programming by solving commonly faced problems with the help of recipes. You will start by installing Go binaries and get familiar with the tools used for developing an application. Once you have understood these tasks, you will be able to manipulate strings and use them in built-in function constructs to create a complex value from two floating-point values. You will discover how to perform an arithmetic operation date and time, along with parsing them from string values. In addition to this, you will cover concurrency in Go, performing various web programming tasks, implementing system programming, reading and writing files, and honing many fundamental Go programming skills such as proper error handling and logging, among others. Whether you are an expert programmer or newbie, this book helps you understand how various answers are programmed in the Go language.</p>

Escaping characters in a string


In this section, we're going to see how to escape special characters in string values. Similar to many other languages in the market today, Go treats certain characters in a special way. For instance, if Go sees \t characters in a string value, it will treat them as a tab character instead. Also, without escaping it, you cannot have double quotes within a double quote, and right now we're going to see how to escape them in order to properly show those characters to our output.

 

 

As always, we will have our main.go file and the main function. So let's check an example that is similar to the previous one.

package main
import "fmt"
func main(){
  helloWorld := "Hello World, this is Tarik."
}

So, if I want to include double quotes around the term Tarik, I can do it, but, as you can see, it gives me a compile time error, as shown in the following screenshot:

So, let's fix this. All I need to do is use \. So, anytime you want to escape a special character, you escape...
