Introduction of Go-Lang
Introduction Go is a procedural programming language. It was developed in 2007 by Robert Griesemer, Rob Pike, and Ken Thompson at Google, but it was officially released in 2009 as an open-source progr
Fundamentals in Go
Identifiers In programming, identifiers are used for naming purposes. Essentially, identifiers are user-defined names for program components. In the Go language, identifiers can represent va
Control Statement in Go
if, if-else, Nested-if, if-else-if Decision-making in programming is analogous to decision-making in real life. In programming, a piece of code executes when a specified condition is met. These constr
Functions & Methods
Functions in Go Language In Go, functions are segments of code designed to carry out specific tasks. They can be reused throughout the program to optimize memory usage, enhance code clarity, and save
Structures in Golang
Structures A structure, or struct, in Go is a user-defined data type that groups together related items of different types into a single type. Any real-world entity with a set of properties
Arrays in Go
Arrays Understanding Arrays in Go Programming Language Arrays in Go (or Golang) are conceptually similar to arrays in other programming languages. They are particularly useful when you need to manage
Slices in Golang
Slices What Are Slices? Key Features: Slice Components: Creating Slices: 1. From Arrays: Use slicing syntax array[low:high]. 2. Slice Literals: 3. Using make(): 4. From Existing Slices: Use
File Handling (Input/Output) in Go (Golang)
Introduction to File Handling File handling refers to the process of creating, reading, writing, updating, and deleting files stored on a computer’s file system. In Go, file handling is part of standa
Pointers in Go (Golang)
A pointer is a variable that stores the memory address of another variable. In Go, pointer types look like *int, *string, *MyStruct, etc. Why pointers are used Pointers are useful when you want: Basic
Concurrency in Golang
Goroutines Goroutines allow functions to run concurrently and consume significantly less memory compared to traditional threads. Every Go program begins execution with a primary Goroutine, commonly re
Object Oriented Programming
Is Go Object Oriented? Go is not considered a pure object-oriented programming language. However, as outlined in Go’s FAQs, it incorporates features that allow object-oriented programming to some exte
Defer and Error Handling
Defer The defer statement in Go is used to execute a function call just before the enclosing function returns. Example 1: Basic Usage of Defer Explanation:In this program, defer&n
First Class Functions
First-Class Functions in Go A language that supports first-class functions allows functions to be: Anonymous Functions Anonymous functions are functions without a name, which can be assigned
Reflection in Go
Reflection A language that supports first-class functions allows functions to be: Why Inspect a Variable’s Type at Runtime? At first glance, it might seem unnecessary to inspect a variable’s
File Handling in GO
Reading Files 1. Reading an Entire File into Memory The simplest file operation is reading an entire file into memory using the os.ReadFile function. Below is an example. Directory Structure
