Go programming

In Go, functions play a crucial role in structuring your code. They are blocks of code that have a specific name and contain a set of instructions. Understanding how to use functions effectively can greatly enhance your programming experience. In this article, we’ll explore the different aspects of functions in Go and how you can use them to your advantage. Defining Functions in Go Let’s start with the basics. In Go, functions are typically defined with a custom name....

In this tutorial, we will build upon what we learned in our previous tutorial on how to create your first Go program. If you haven’t read it yet, you can find it here. To compile and run a Go program, follow these steps: Open a terminal in the hello folder where your Go program is located. Use the go run command to compile and run the program. Enter the following command in the terminal: go run hello....

In this tutorial, we will guide you through creating your first Go program. By convention, the first program typically prints the “Hello, World!” string to the terminal. Let’s get started! If you have a folder in your home directory where you keep all your coding projects and tests, go ahead and create a new folder called hello. Inside the hello folder, create a new file named hello.go (you can give it any name you prefer)....

In Go, a function can be assigned to a struct, giving it the ability to perform actions related to its data. This concept is known as a method. Let’s take a look at an example: type Person struct { Name string Age int } func (p Person) Speak() { fmt.Println("Hello from " + p.Name) } func main() { flavio := Person{Age: 39, Name: "Flavio"} flavio.Speak() } In this example, we define a Person struct with two fields, Name and Age....

Strings in Go are a fundamental data type used to represent a sequence of byte values. In this article, we will explore various aspects of working with strings in Go and discuss some useful techniques and functions. Defining a String To define a string in Go, you can use double quotes (") as shown below: var name = "test" Unlike some other programming languages, Go only supports double quotes for defining strings, not single quotes....
