In the Go programming language, input and output (I/O) operations are performed using the fmt, bufio, and os packages. 🔹 1️⃣ Output in Go Go provides multiple ways to display output using the fmt package. ✅ fmt.Print(), fmt.Println(), and fmt.Printf() Function Description fmt.Print() Prints text without a newline fmt.Println() Prints text and adds a newline […]
This project will help you build a basic HTTPS server using Go's net/http package. The goal is to serve a simple webpage and handle both GET and POST requests, while also leveraging goroutines to handle concurrent requests. Core Concepts: Project Overview: Step-by-Step Code Implementation: Full Code Example: Explanation: Running the Server: Conclusion: This is a […]
Here’s how you can create a command-line application in Go to manage a to-do list with the ability to add, remove, and list tasks, and save tasks to a file (JSON or text). Key Concepts: We'll use JSON file format for saving tasks as it’s more structured than plain text. Step-by-Step Guide: 1. Define Task […]
In Go, CSV (Comma-Separated Values) files are a common format for storing tabular data. The encoding/csv package in Go allows you to read and write CSV files efficiently. Below, we'll explain how to read from and write to CSV files in Go. 1️⃣ Reading CSV Files To read a CSV file in Go, we use […]
In Go, JSON and XML are common data interchange formats. The encoding/json and encoding/xml packages are used to work with these formats. These packages allow you to parse, encode, and decode JSON and XML data. Below, we will look at examples of working with both JSON and XML in Go. 1️⃣ Working with JSON JSON […]
In Go, file handling is done using the os and io/ioutil packages. These packages provide functions for reading from and writing to files, which allows Go programs to interact with the file system. The basic operations include opening, reading, writing, and closing files. 1️⃣ Reading Files in Go To read from a file in Go, […]
In Go, panic and recover are mechanisms for handling unexpected situations or errors that might cause your program to crash. They allow you to handle critical errors that would otherwise stop the program. However, using them requires caution, as they can interrupt the normal flow of your program. 1️⃣ Panic in Go When a function […]
Custom error handling is an important aspect of Go, allowing you to define your own error types and handle errors more flexibly. You can create custom error types to provide additional context or include more detailed information, making error messages clearer and more informative. 1️⃣ Creating Custom Error Types You can create a custom error […]
In Go, error handling is an essential part of writing robust programs. Unlike many programming languages that use exceptions, Go uses a more explicit approach by using the error type to represent errors. The error type in Go is actually an interface, which means it defines a set of methods that types must implement in […]
In Go, WaitGroups and Mutex are two important synchronization mechanisms used to coordinate the execution of concurrent goroutines. They help in managing the flow of goroutines, ensuring that tasks are completed or data access is controlled appropriately. 1️⃣ WaitGroups A WaitGroup is used to wait for a collection of goroutines to finish executing. It allows […]
