What is a Pointer? A pointer is a type of variable that stores the memory address of another variable. Rather than containing an actual data value, a pointer contains the specific location in memory where the data value is stored.This…

What are Bytes? In computing, a byte represents a unit of digital information storage that is capable of holding a single character. It consists of 8 bits and can store values ranging from 0 to 255. Bytes are the building…

The utilization of the var keyword in Golang programming allows for the explicit declaration of variables.In Golang, the storage and manipulation of data heavily rely on variables. The var keyword serves the purpose of explicitly declaring variables, requiring the specification…

1. Introduction In Golang, strings are essentially immutable byte slices that can store diverse data types beyond traditional text formats like UTF-8. When indexing a string, you directly access individual bytes, demonstrating Golang's straightforward approach. Unicode code points are represented…

In Golang, converting strings to integers is crucial. Golang offers specific methods for this task. This blog focuses on string to integer conversion in Golang, exploring strconv.Atoi, strconv.ParseInt and fmt.Sscan. Understanding these methods' strengths will improve your code's performance and…

Fibonacci Numbers Sequence The mathematical number series is initiated with its initial two numbers such as 0 and 1. Each subsequent number in the mathematical sequence is the sum of the two previous numbers. This mathematical series is known as…

Introduction Automating tasks is a crucial aspect of software development, and cron jobs are a popular way to schedule these tasks. In this tutorial, we'll show you how to create and manage cron jobs in Golang using the robfig/cron package.…

Introduction WaitGroups in Go (Golang) is a powerful synchronization primitive provided by the sync package. It ensures that your program waits for a collection of goroutines to finish executing, preventing premature exits or progression while goroutines are still running. Before…

Introduction The Go build command in Go is indispensable for compiling your code along with its dependencies into an executable file. Its primary objective is to convert Go source code into a functional program. This command offers flexibility, enabling you to…

Prerequisites Knowledge of Goroutines and Channels Introduction The "select" statement in the Golang programming language is a powerful tool for handling multiple channel operations simultaneously.It allows a Golang program to wait for multiple communication operations to complete and proceed when…
