In golang, promoted fields are the structs that are embedded inside another structs and their fields can also be accessed the structs in which they are embedded. In this article we are going to understand three different approaches to depict use of promoted filed with and without the help of ... Read More

In golang, a rand package is used to generate random numbers/characters. Firstly, it seeds with the current time to get the different random Output each time then perform any operation. Syntax rand.Seed(value) Rand.Seed() function is used to generate random numbers. It takes a user input as argument which is ... Read More

In this article, we will write Go language programs to show scope of global and local variables using pointer approach. Scope is referred to as the accessibility of the piece of code in the program in particular function. Scope can be defined in two ways: globally and locally. Global means ... Read More

In this Golang article, we will write programs to print struct variables. Here, there is no concept of classes, instead of that structs are used to represent a collection of related fields or properties. Using Name of the Field and Shorthand Declaration in the Main Function In this method, ... Read More

In golang we can create a module with variable using const or var keywords, orelse we can even import the module . A module in Go is a group of packages. It helps in managing the distribution of the package. Algorithm Step 1 − Create a package main and ... Read More

In this article we will write a Golang program to create a class inside the module. There are no classes only structs are used in this program which will contain the data fields. A module is a collection of the packages having go.mod file at its root. This file determines ... Read More

In this article, we will write a Go language programs to check a hash collection is empty or not. A hash collection is a data structure that contains key-value pairs in Go (Golang) and enables quick lookups, additions, and deletions. The value that corresponds to the key can be accessed ... Read More

In Golang we can use delete keyword or empy map to remove all the elements from hash collection. Hashmap is a data structure from hash collection. It is an implementation of hash table which takes O(1) constant time to execute. In this program we will remove all items from hash ... Read More

In Golang we can use various internal functions or packages like len() function or reflect package, to get the size of the hash collection. A Hash collection contains a hashmap which is generally used to create key:value pairs and on the basis of that it shortens the execution time. In ... Read More

In this article, we will write Golang programs to search an item in the hash collection. A hashmap is part of hash collections. Here we are building a hashmap as set of key-alue pairs using Golang’s map which is constructed using map literal. We will execute this program using two ... Read More
