How to compare Structs with the Different Values Assigned to Data Fields in Golang?
When working with Go, it's often necessary to compare structs to determine whether they're equal or not. Comparing two structs can be easy when they have the same values assigned to their data fields. However, comparing structs with different values assigned to their data fields can be a bit more complicated. In this article, we'll discuss how to compare structs with different values assigned to their data fields in Golang. Comparing Structs with the Same Values Assigned to Data Fields Before we dive into comparing structs with different values assigned to their data fields, let's first take a look at ...
Read MoreHow to Compare Equality of Struct, Slice and Map in Golang?
Golang is a statically typed language that provides developers with a range of built-in data types to work with, including structs, slices, and maps. Comparing the equality of these data types can be a bit tricky, as they have different underlying implementations. In this article, we'll discuss how to compare equality of struct, slice, and map in Golang. Comparing Equality of Structs in Golang Structs are composite data types that allow you to group together related values. When comparing two structs in Golang, you need to compare each field of the struct separately. You can do this by using the ...
Read MoreHow to check pointer or interface is nil or not in Golang?
In Golang, we often come across situations where we need to check whether a pointer or interface is nil or not. A pointer is a memory address pointing to a variable or data type, while an interface is a set of methods that define a particular behavior. In this article, we will discuss how to check whether a pointer or interface is nil or not in Golang. How to check if a pointer is nil or not in Golang? To check whether a pointer is nil or not in Golang, we can use the comparison operator ‘==’ to compare it ...
Read MoreHow to check equality of slices of bytes in Golang?
In Golang, checking the equality of slices of bytes is a common task when working with binary data or network protocols. In this article, we will discuss how to check the equality of slices of bytes in Golang using different methods. Method 1: Compare Each Element of the Slices One way to check the equality of slices of bytes in Golang is to iterate over each element of the slices and compare them one by one. This can be achieved using a simple for loop, as shown in the following code example − Example package main import "fmt" ...
Read MoreHow to Assign Default Value for Struct Field in Golang?
In Golang, it is common to have struct types that need to be initialized with default values. In this article, we will explore how to assign a default value for a struct field in Golang. Assigning Default Values for Struct Fields To assign a default value for a struct field in Golang, we can define a default value for the field during the struct type declaration. For example, consider the following struct type − type Person struct { Name string Age int Address string ...
Read MoreHow to append a slice in Golang?
Appending a slice in Golang is a common operation when working with collections of data. In this article, we will explore how to append a slice in Golang. Syntax for Appending a Slice in Golang slice = append(slice, element) The append() function in Golang appends the given element(s) to the end of a slice and returns a new slice. If the original slice has enough capacity to hold the new elements, the underlying array is reused, else a new array is allocated. Example Here's an example of how to append a slice in Golang. package main import ( ...
Read MoreHow Many Logical Processors Used By Current Process in Golang
In modern computing, multi-core processors are ubiquitous, which can execute multiple tasks simultaneously. In Golang, we can take advantage of this by using concurrency to perform tasks in parallel. However, how can we determine the number of logical processors used by the current process? In this article, we will discuss how to find out the number of logical processors used by the current process in Golang. Using the Runtime Package The Go programming language provides the runtime package, which includes functions that allow us to control and interact with the Go runtime environment. One of these functions is runtime.NumCPU(), which ...
Read MoreHigher-Order Function in Golang
Higher-order functions are a powerful feature of modern programming languages, including Golang. In this article, we will discuss what higher-order functions are and how they can be used in Golang. What is a Higher-Order Function? A higher-order function is a function that takes one or more functions as arguments and/or returns a function as its result. This means that higher-order functions can be used to create new functions that are tailored to specific needs, making code more efficient and reusable. Higher-Order Function Example in Golang Let's consider a simple example to understand how higher-order functions work in Golang. Suppose we ...
Read MoreGolang Program to Check if the String is Alphanumeric
In Go programming language, it is essential to check if a string contains alphanumeric characters or not. Alphanumeric characters are a combination of alphabets and numbers, and they are commonly used in passwords, usernames, and other important data. In this article, we will discuss how to write a Golang program to check if a string is alphanumeric. What is an Alphanumeric String? An alphanumeric string is a string that contains a combination of alphabets and numbers. It can also include special characters such as underscore (_) and dash (-), but not all special characters are considered alphanumeric. Alphanumeric strings are ...
Read MorePosition of n among the numbers made of 2, 3, 5 & 7
The problem statement includes printing the position of n among the numbers made of 2, 3, 5 and 7, where n will be any positive number given by the user. The numbers made of 2, 3, 5 and 7 means this will be the sequence of the strictly increasing numbers which comprises only digits 2, 3, 5 or 7 i.e. first four prime numbers. The first few numbers of the sequence where all numbers have only 2, 3, 5 and 7 as their digits are 2, 3, 5, 7, 22, 23, 25, 27, 32, 33, 35, 37, and so on. ...
