Generate UUID in Golang
Universally Unique Identifier (UUID) is a 128-bit value that is used to uniquely identify objects or entities. UUID is widely used in computer systems for generating unique IDs for objects, documents, and data records. In Golang, we can generate UUID using the "github.com/google/uuid" package. Installing the "github.com/google/uuid" Package Before we can generate UUID in Golang, we need to install the "github.com/google/uuid" package. To install this package, run the following command in the terminal − go get github.com/google/uuid Generating UUID in Golang Once we have installed the "github.com/google/uuid" package, we can use the "uuid" package to generate UUIDs. Here's an ...
Read MoreGetting the current date and time with timestamp in local and other timezones in Golang
In Go, it's easy to work with dates and times using the time package. This package provides a set of functions and types for working with dates and times, including the ability to get the current date and time with a timestamp in local and other timezones. In this article, we'll explore how to get the current date and time with a timestamp in local and other timezones using Go. Getting the current date and time with timestamp in local timezone To get the current date and time with a timestamp in the local timezone, we can use the time.Now() ...
Read MoreGolang program that uses structs as map keys
Golang is a powerful programming language that provides a variety of features to work with structured data. One of these features is the ability to use structs as keys in maps. In this article, we will explore how to write a Golang program that uses structs as map keys. What is a Struct? In Golang, a struct is a composite data type that groups together zero or more values of various types. Structs are used to create more complex data types that can represent a range of objects. A struct is defined using the type and struct keywords, followed by ...
Read MoreGolang Program that uses String Switch
Golang is a popular programming language that offers a range of powerful features. One of these features is the ability to use the switch statement with a string type variable. In this article, we will explore how to write a Golang program that uses a string switch statement. What is a String Switch? In Golang, the switch statement can be used to test a variable against a list of values. A string switch statement is a type of switch statement that is specifically designed to work with string variables. A string switch statement works by comparing the value of a ...
Read MoreGolang Program that Uses Named Return Values and Defaults
Golang is a powerful programming language that offers a range of features and tools for building efficient and reliable applications. One such feature is the ability to use named return values and defaults in functions. In this article, we will discuss how to use named return values and defaults in Golang and why this feature is useful. What are Named Return Values and Defaults in Golang? In Golang, you can define named return values in a function signature, which can help make your code more readable and maintainable. Named return values allow you to define the names and types of ...

Golang is a popular programming language that offers a range of features and tools for building efficient and reliable applications. One such feature is the ability to use functions as local variables. In this article, we will discuss how to use functions as local variables in Golang and why this feature is useful. What are Local Variables in Golang? Before we dive into how to use functions as local variables in Golang, let's first understand what local variables are. In programming, a local variable is a variable that is defined within a function or block of code. Local variables are ...
Read MoreGolang program that uses fallthrough keyword
Golang is a powerful programming language that has gained a lot of popularity in recent years. It offers many features and tools that make it easier for developers to create efficient and reliable applications. One of the features that sets Golang apart from other programming languages is the fallthrough keyword. In this article, we will take a look at how you can use the fallthrough keyword in your Golang programs. What is the Fallthrough Keyword in Golang? In Golang, the fallthrough keyword is used in switch statements to transfer control to the next case statement. When a case statement contains ...
Read MoreGolang Program that switch on floating-point numbers
In Go, the switch statement can also be used with floating-point numbers. This feature can be useful in certain scenarios, where a floating-point value needs to be compared against different thresholds or ranges. In this article, we will go through an example program that demonstrates the use of switch statement on floating-point numbers. Syntax of Switch Statement with Float The syntax of switch statement with floating-point numbers is the same as that with any other type. The only difference is that the cases need to be specified as floating-point values. switch expression { case value1: ...
Read MoreSplitting a slice of bytes after the specified separator in Golang
In Golang, it is often required to split a slice of bytes after a specific separator. This can be done using the built-in function bytes.SplitAfter(). This function splits a slice of bytes into sub-slices after each occurrence of a specified separator. In this article, we will discuss how to split a slice of bytes after a specific separator in Golang. Syntax of bytes.SplitAfter() The syntax of the bytes.SplitAfter() function is − func SplitAfter(s, sep []byte) [][]byte where s is the slice of bytes to be split, and sep is the separator. Example package main import ( ...
Read MoreSearching an element of int type in slice of ints in Golang
Slices are an essential feature of Go programming language that allows you to store and manipulate an ordered collection of elements. Slices are similar to arrays, but unlike arrays, they are dynamic and can be resized. In Go, you can perform a search operation on a slice to find an element or a set of elements. This article will guide you through the process of searching for an element of int type in a slice of ints in Go. Searching an element of int type in slice of ints in Golang To search for an element of int type in ...
