In Go, methods are functions that are associated with a specific type. They allow developers to define behavior for objects of that type. In this article, we will explore the basics of methods in Go, how to define and use them, and the different types of methods available. Defining Methods in Golang In Go, methods are defined by associating them with a type using the following syntax − func (receiver type) methodName(parameters) returnType { // method body } The "receiver" is the type that the method is associated with. It can be a value or a ... Read More
Matching using regular expressions, or regex, is a common task in programming. Go, also known as Golang, provides a built-in package called "regexp" that allows developers to use regular expressions in their programs. In this article, we will explore how to use regular expressions in Go and the different functions and methods available in the "regexp" package. What is Regular Expression? A regular expression, or regex, is a sequence of characters that define a search pattern. Regular expressions are used to search, replace, and manipulate text. They are a powerful tool for text processing and data validation. Using Regexp in ... Read More
There are two types of headphones namely, noise-cancelling headphones and noise-isolating headphones, which are designed to suppress the unwanted external noise in the sound. But both are completely different from each other. The main difference between noise-cancelling and noise-isolating headphones is that the noise-cancelling headphones actively reduce external noise by using microphone and electronics, while the noise-isolating headphones create a physical barrier between the ear and the surrounding noise to block the external noise. In this article, we will discuss all the important differences between noise-cancelling and noise isolating headphones. But before that let us first have a ... Read More
Display is the most important part of a visual display unit (VDU) like TV, monitor, etc. Depending on the colors displayed on the screen, displays are of two types namely, monochrome display and color display. The fundamental difference between monochrome and color display is that a monochrome display can display graphics like images, text, etc. in gray shades only, while a color display can display graphics in full color. In this article, we will discuss all the important differences between monochrome display and color display. But before discussing the differences, let us first have a look into their basics. ...

Loop control statements are used in programming languages to control the flow of loops. These statements help developers to execute certain conditions during loop execution. Go, also known as Golang, is a popular open-source programming language that provides three loop control statements: break, continue, and goto. In this article, we will explore each of these statements in detail and their usage in Go. The Break Statement The break statement is used to terminate a loop prematurely. It is usually used when a specific condition is met, and there is no need to continue iterating. The following example shows the usage ... Read More
USB stands for Universal Serial Bus. USB is a modern communication interface used in computers and other electronic devices for connecting peripherals such as mouse, keyboard, etc. Today, USB has become a standard protocol for connections in electronic devices. USB was first introduced in mid-1990 and has become popular due to its plug and play feature. The USB interface allows peripheral devices to connect to and disconnect from electronic devices without the requirement restarting of the device. USB interface uses Bus Network Topology, allowing multiple devices to connect to a single USB port through a USB hub. Several types of ... Read More
The inverse error function (erf⁻¹) is the inverse function of the error function (erf) which is used to calculate the probability of a normally distributed random variable falling within a certain range of values. In this article, we will discuss how to calculate the inverse error function of a given number using Golang. Understanding the Error Function Before we dive into the inverse error function, it is important to understand what the error function is and how it works. The error function is defined as − erf(x) = (2/√π) ∫₀ ˣ e⁻ᵗ² dt This function is used to ... Read More
Interfaces in Golang are a powerful feature that allows developers to define a set of methods that must be implemented by any type that satisfies that interface. Interfaces help to make code more modular, reusable, and easier to maintain. In this article, we will explore interfaces in Golang, how to create them, and how to use them effectively. What are Interfaces in Golang? An interface in Golang is a collection of method signatures that define a set of behaviors that a type must support to satisfy that interface. In other words, an interface defines what methods a type must have ... Read More
TV, Television, is a well-known electronic device used to display audio-video content on a screen. Based on display technology used, several types of TVs available, such as LCD TVs, LED TVs, Plasma TVs, CRT TVs, etc. In this article, we will discuss the important differences between LED TV and Plasma TV. But before that let us first have a look into the basics of LED TV and Plasma TV individually. What is LED TV? A type of TV in which LEDs (Light Emitting Diodes) are used to illuminate the display screen is called LED TV. LED TV is basically ... Read More
Go is a popular programming language that is designed to be efficient, readable, and simple. One of the key features of Go is its ability to manage external packages and dependencies, which is done through the use of import statements. In this article, we will discuss the basics of importing packages in Go, and how to use them in your programs. What is an Import Statement in GoLang? In Go, an import statement is used to access external packages or dependencies in your code. An import statement specifies the name of the package you want to import and the location ... Read More
