Arrays and Structures are two different types of container datatype. The most basic difference between an array and a structure is that an Array can contain the elements of same datatype, while a Structure is a collection that can contain the elements of dissimilar datatypes. Read this article to learn more about Arrays and Structures and how they are different from each other. What is an Array? An array refers to a collection that consists of homogenous elements, i.e. of same data type. Arrays are declared using '[]'. It uses subscripts/ '[ ]' (square brackets) to access the elements. An ... Read More

Recursion and Iteration both repeatedly execute the set of instructions. Recursion occurs when a statement in a function calls itself repeatedly. The iteration occurs when a loop repeatedly executes until the controlling condition becomes false. The basic difference between recursion and iteration is that recursion is a process always applied to a function and iteration is applied to the set of instructions which we want to be executed repeatedly. Read through this article to find out more about Recursion and Iteration and how they are different from each other. What is Recursion? Recursion is defined as a process in which a function calls itself repeatedly. Recursion uses selection structure. If the recursion step does ... Read More

Data Hiding and Encapsulation are important concepts in object-oriented programming (OOP). Data hiding helps prevent the illegal or unauthorized access of members of a class, while encapsulation helps in the wrapping up of data members and methods inside a class. The most basic difference between data hiding and encapsulation is that data hiding focuses on data security, while encapsulation focuses on hiding the complexity of the system. Read this article to find out more about Data Hiding and Encapsulation and how they are different from each other. Let's start with a basic overview of these two important concepts, Data Hiding ...

A collection framework in Java consists of a set of classes and interfaces which helps in implementing various data structures. List and ArrayList belong to this collection framework. List is an interface and ArrayList is a class. Their main motto is to create a list data structure. List is a collection of ordered elements arranged using the concept of indexing. Arrays use the concept of dynamic array to store elements. What is a List in Java? A list is one of the interfaces of the collection framework. It stores objects in an ordered manner. Here, the elements are stored sequentially. ... Read More

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 this post, we will understand the difference between HTML and CSS HTML HTML refers to Hyper Text Markup Language. It helps create web pages and applications − It helps define structure of web page. It is a markup language. It helps create static pages as well. It helps display data. HyperText helps define link between multiple web pages. Markup Language helps define text document using tags, which gives a structure to the web page. It has less backup and support options. HTML can’t be used inside a CSS sheet. It helps annotate the text so that a system ... Read More

The task of arranging elements of an array in a particular order is referred to as sorting. The sorting of an array or a list is mainly done to make the searching easier. There are two types of sorting algorithms namely, Bubble Sort and Selection Sort. Bubble sort performs sorting of data by exchanging the elements, while the selection sort performs sorting of data by selecting the elements. Read this article to learn more about bubble sort and selection sort and how these two sorting techniques are different from each other. What is Bubble Sort? Bubble sort is a simple ... Read More

There are two types of non-linear data structures namely, B-Tree and Binary Tree. These two terms sound similar but they are absolutely different from each other. The most basic difference between a B-Tree and a Binary Tree is that a B-Tree is used for data storage on a disk, whereas a Binary Tree is used for data storage in RAM. Read this article to learn more about B-tree and Binary Tree and how they are different from each other. What is a B-Tree? B-Tree, also called Balanced Sort Tree, is a type of balanced M-way tree. In a B-tree, the ... Read More

Both Trees and Graphs are types of non−linear data structures. They are different from each other in the context of their types of connections and loop formation. That means, a tree structure is connected such that it can never have loops, whereas a graph structure follows a network model and may have loops. Read this article to find out more about Tress and Graphs and how they are different from each other. What is Tree? A Tree is a non−linear data structure that is used to represent hierarchy. It is a set of nodes that are joined together to ... Read More

The realm of computer graphics is an expansive one that is always undergoing development. It involves a variety of concepts and ideas, of which "drawing a line" is the most fundamental tasks involved in working with graphical media.There are two algorithmic rules that are followed while drawing a line on the screen. They are DDA (Digital Differential Analyser) algorithmic rule and Bresenham line algorithm.Both the DDA and Bresenham's algorithm are examples of computational procedures that can be utilised for the goal of approximating the length of a line segment.What is DDA?The primary purpose of a DDA in computer graphics is ...
