      SDLC Methodology

      SDLC (Systems Development Life Cycle) is the process of creating or modifying existing systems and the models and methodologies that are used in the process. In the fields of software engineering and information systems, SDLC denotes a framework of methodologies aimed at the creation of an information/software system, i.e. the software development process. SDLC covers

    • Circular Queue

      Circular Queue

      The difficulty of managing front and rear in an array-based non-circular queue can be overcome if we treat the queue position with index 0 as if it comes after the last position (in our case, index 9), i.e., we treat the queue as circular. Note that we use the same array declaration of the queue.

    • Depth First Search Algorithm

      Depth First Search Algorithm

      A DFS algorithm, as the name implies, is used to search deeper in the graph, whenever possible. The edges are explored, out of the most recently discovered vertex v that still has unexplored edges leaving it. When all of v's edges have been explored, the search backtracks to explore edges leaving the vertex from which

      What Are the Benefits of PHP?

      The programming language called PHP is quickly rising to be one of the most preferred web browser programming languages due to its user-friendliness, efficiency, and user control. PHP allows a user to describe specific functions within the code in order to drastically control the way a web browser displays and organizes information. A user is

    • Change TextBox Width with JQuery on Focus and Blur

      Let’s see how can we change the width of any HTML TextBox using JQuery on occurrence of following 2 actions: Focus and Blur. Focus is when you click anywhere inside a TextBox and Blur is when a TextBox isn’t active or focused. Prerequisite: JQuery Library should already be included in the page. Consider we have

    • Constructors that Allocate Memory Dynamically

      Constructors that Allocate Memory Dynamically

      Constructors can be used to initialize member objects as well as allocate memory. This can allow an object to use only that amount of memory that is required immediately. This memory allocation at run-time is also known as dynamic memory allocation. The new operator is used for this purpose. Sample Program The program below shows

    • How to Debug Java

      How to Debug Java

      The ability to debug any modern programming language is a critical skill for programmers of all skill levels. Learning how to debug Java helps developers discover the causes of logic and non-trivial syntax errors that prevent proper execution of Java programs. The ability to step-through a Java program using a debugging environment provided by updated

    • Binary Tree – Deleting a Node

      Binary Tree – Deleting a Node

      The possibilities which may arise during deleting a node from a binary tree are as follows: Node is a terminal node: In this case, if the node is a left child of its parent, then the left pointer of its parent is set to NULL. Otherwise if the node is a right child of its

    • Doubly Linked List

      Doubly Linked List

      In a doubly linked list, also called a two-way list, each node is divided into three parts: The first part, called the previous pointer field, contains the address of the preceding element in the list. The second part contains the information of the list. The third part, called the next pointer field, contains the address

    • Disassembler

      Disassembler

      A disassembler is a software that is able to convert an executable language into an assembly language, allowing users to view the individual commands that make a program work. A disassembler is ideal for programming applications because it can be useful when a programmer is attempting to create a similar program to one he/she already
