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

Printing data to the console is an essential task that not only helps debug the code but makes us write good code. In this post, we are going to take a look at the Println() function in Golang, which is a variadic function. Golang Println() Method Signature The method signature of the Println function is

String formatting is essential when we need to create a string dynamically. String formatting makes our lives easier by allowing us to do things that can take much longer if done some other way. For example, we need to print a hex value of a number. Using string formatting it is a lot easier. In

String splitting is a task that is needed when we want to manipulate strings. When data comes in a long string, we may need to split it into the required pieces. One of the very common use case is splitting a CSV string into different values based on the delimiter. In this post, we will

We need random numbers for a lot of reasons. It may be due to some basic reason or cryptographic. Complete random number although is not possible to generate but pseudorandom numbers can be used in their place. The pseudorandom numbers are a deterministic sequence of numbers that depends on a seed value. In this post,

Comparing strings together is an important task that is almost unavoidable in large programs. In this post, we will see different ways of comparing strings in Golang. 1. Using the Golang Comparison Operators There is a multitude of comparison operators in Go. Each operator works in the way it looks. We will see what are
