The basic difference between an array and a linked list is in their structure. An array relies on the index-based data structure, whereas a liked list is based on the references. Read this article to find out more about Arrays and Linked Lists and how they are different from each other. What is an Array? An array is a consistent set of fixed number of data items. Array stores elements in contiguous memory locations. This means the specific elements can be accessed using easily calculable addresses. Hence, an array provides fast access to find element at a specific index. Another ... Read More
In Go programming language, string interpolation is the process of integrating expressions into a string literal. When it's necessary to include dynamic values in strings for log statements, error messages, and other purposes, string interpolation is frequently used. We will use two methods in this program to demonstrate string interpolation. The first example demonstrates use of sprintf and the second example shows how to use printf to execute string interpolation. Method 1: Using sprintf with fmt package In this method, the name and age variables' values are combined into a string using fmt.Sprintf() function which demonstrate interpolation. Here, Strings are ... Read More
Alpha and Beta testing are types of testing which are based on feedback from real customers using real products in real environments, but they are driven by distinct goals and processes. Read this article to find out more about Alpha and Beta testing and how they are different from each other. What is Alpha Testing? Alpha testing is the testing that is performed at the developer's site by the internal teams, before releasing the product to the external customers. The primary goal of alpha testing is basically to find bugs, and determine does the product work how it is expected ... Read More
In Golang, a string cannot be modified after they have been created. A built-in type in Go, the string type can be used in a variety of ways much like any other data type. In this article, we will use three methods to create a string object. The first method involves using of double quotes and backticks, in the second method strings.Replace() function is used and in the third method, a byte function is used to execute the program. Method 1: Using double quotes and backticks Two string objects, str1 and str2, are created in this program. Backticks (') are ... Read More
In Golang, a vector is referred to as an array or a slice. Slice is a dynamic array whose size can be changed whereas a linked list data structure is one type of list, where each node has a value and is pointing to the next element. We will use two examples in this program to convert vector to a list. In the very first example a built-in copy function will be used and in the second example we will iterate the slice in the reverse order to obtain the output. Method 1: Using Copy Function In this method, we ... Read More
In this Golang program, converting primitive data types (such as int, char, float, etc) to objects is known as "Boxing". It is a procedure that transforms a primitive type into the matching object type, such as an integer into a float, a character into a char, etc. This enables the programmer to use the fields and methods of the relevant object type and treat primitive data types as objects. We will use two methods to execute this program. Method 1: Using Reflect In this method, the primitive types are transformed into objects using the reflect package. The type and data ... Read More
Have you ever wondered how routers perform various tasks for us? For example, when searching for something on the Internet or fetching some data, routers perform some functions. There are different ways to do the same function as we do in day-to-day life. Similarly, routers also have different ways of delivering the data packets to us. Two such ways are − Adaptive or Dynamic Routing algorithms, and Non-Adaptive or Static Routing algorithms. Read this article to find out more about adaptive and non-adaptive routing algorithms and how they are different from each other. What is Adaptive Routing Algorithm? ... Read More
In Go programming language, a constructor is a specific kind of function used to initialize an object's state when it is initially formed. It is used to initialize variables and provide data for the objects. We will execute this program using two methods and we will use struct in both of these examples with anonymous struct in the second example. Let’s see through these examples to understand how the program is executed. Method 1: Using a function that returns a desired type In this method, to construct a new Child struct, the NewChildWithAge function runs the NewChildfunction, sets the age, ... Read More
In object oriented programming (OOP), abstraction and data hiding are two important concepts. Abstraction is a process of extracting important information without involving the complete detail of the system. On the other hand, data hiding is a process of wrapping the data in a single unit, i.e., to achieve data encapsulation. Read this article to learn more about abstraction and data hiding and how these two concepts are different from each other. What is Abstraction? Abstraction, or data abstraction, is one of the object-oriented methodologies. Abstraction is defined as the process of hiding the internal implementation and keeping the complicated ... Read More
