Golang

Sorting is an essential operation for many algorithms. Go provides sorting functions for many different data types. In this post, we will discuss about Golang sort package, which is used to sort elements in an array, list, slice, etc. Importing Golang sort Package To sort data types in Go we need to import the sort […]

Arrays are one of the most important data structures in programming. In this post, we are going to see how to find the length of an array in Golang. Golang Array Length using len() function Golang len() function is the simplest way to find the length of an array in Go. Here it is in

Bytes are a data type in Golang. In this post, we will explore bytes as well as slices of them, the bytes package itself and what can be done with it. What is a byte variable? A byte in Go is simply an unsigned 8-bit integer. That means it has a limit of (0 –

The init function is a powerful function in Go. It allows doing things like initialization of a package that otherwise really hard to achieve. In this post, we are going to take a look at Go’s init function. What is the init function in Golang? The init function is a function that takes no argument

Methods are just like functions, except it has a special argument and that is a receiver. In this post, we will dive deeper into Golang methods. Golang Methods Syntax A method consists of the func keyword, the receiver argument, and the function body. Here is the syntax of a Go method. So, when we want

Pointers are one of the most important building blocks of writing good code. In this post, we are going to explore pointers, what they are, and how can they be used in Go to write excellent code. 1. What is a pointer? A pointer is a variable that stores the address it points to. A

The if-statement is present in almost every programming language out there. It is one of the most important control-flow statements in programming. In this post, we will explore the different ways we can use the if statement to make our programs robust and concise. 1. The syntax of if-expression in GoLand The syntax of the

Deleting files is important when we want to do routine work with files. E.g. we save some log data and then after some time we may want to remove it automatically. This file deletion can be easily done in Go. In this post, we are going to discuss how to delete files in Go. Remove

In this post, we are going to explore how to write into files in Golang. Go has the io, os, and ioutil (deprecated in Go1.16) package which makes writing a file a lot easier. So, let’s see what are the different ways we can do it. First step: Creating a File In order to write

Reading files is one of the most essential tasks in programming. It allows us to see content, modify and write it using programming. In this post, we will see how to read file contents in Go. 1. Open a file for reading The first step is to open the file for reading. We can use
