Well, the answer to all these questions is Data Abstraction in DBMS. With the help of data abstraction, developers customize what you can view and what other users can view on the website or application. If you are a budding developer, data abstraction is one such concept that you must not miss out on. Therefore, we have come up with a complete guide on what is data abstraction in DBMS , how to use it and why you need it. What Is Data Abstraction? Data abstraction  is a process to hide irrelevant data from the user or system. The main motive behind this process is to provide different views and implement data independence. Data abstraction is generally used to boost the security of the data and makes it simpler to work with complex databases. The main purpose of using data abstraction is to divide the given problem into smaller subproblems so as to easily manage the data. It keeps irrelevant data or information hidden from the user to make things and applications more user-f...

  Not many people trust downloading various software into their PCs for safety reasons. In such cases, using the online version of the same can be extremely beneficial. That way, you do not miss out on any of the features and still have almost the same experience. One such example can be seen in the increasing use of online Java compilers. Traditionally, programmers had to download different software for compiling their codes, but now, they have another option. Online java code compiler. But why should one use the online platform? That is what we will be discussing in this blog. What is a Java compiler? Before we dive in, let's know what a Java compiler is. When a programmer writes code in Java, it has many words and elements that a machine cannot understand, i.e. the computer. Thus, the programmer needs to compile the code into a machine-friendly language. This enables the computer to understand it and later execute it. And for compiling the java code, the programmer uses a compi...

  Be it game programming or any other application that brilliant tech companies develop, C language is a fundamental necessity in achieving that. This language usually forms the basis of any other higher languages available. Some people directly hop into advanced languages, which involves more effort if they are not well-versed in C from the beginning.  Do you want to know about all those high-level languages? Well, it’s best to start with the C language because by doing so, you would already know the initial 20% of the most prominent languages, such as Python. This language is the oldest and most basic language that is broadly used all over the world. Many leading tech companies like Microsoft use the C language if they work with some OS Modules. Part of the reason for its wide usage is also that it is a memory and speed-efficient language. Online C Compiler is used to make programs in the C language. Have you heard of the word compiler before? If not, this blog is there to h...

  Algorithms are an integral part of the internet and search engine platform which enhances your search and also is responsible for boosting page rankings online. So what are Algorithms? Algorithms are a set of instructions that solve problems. They can be applied to any problem and have various applications. There are  various types of algorithms , which can be divided into two categories: search and divide and conquer (DC).  Search algorithms help us find something in an array or table, and DC algorithms help us solve problems by breaking them down into smaller pieces and solving them one at a time. Search algorithm The search algorithm is a process that helps in finding the location of an element in an array. A search algorithm can be defined as a computer program that solves a problem by scanning through all possible results that best suit your search query.  The simplest example could be when you want to find out how many numbers there are between 1 and 100: - Y...

HTML is a term you may have come across quite a times as a budding programmer . Did you know that HTML is an acronym for HyperText Markup Language?  It is the code that is used to structure a web page and its content. This is a very important topic in web design and development because HTML is what makes up the basic interface of the internet.  The basic fundamental of html is made up of the following parts: Headings, paragraphs, links, images, videos, and forms. It also has a lot of other features that are used to make websites interactive. While we are on the subject of creating interactive websites, JavaScript is another programming language that is used to create interactive websites and web pages. We have discussed briefly about the basics of JavaScript in the blog. What is HTML? HTML is a language designed for web page creation. HTML is considered a standard markup language for website creation. HTML was invented in 1990 by Tim Berners-Lee. HTML was an early hypertext...

  Introduction Are you scratching your head in confusion because you do not know which sorting algorithm has the best asymptotic runtime complexity?   Algorithm comparisons are based on asymptotic runtime complexity. Since absolute times are hardware-specific, comparing them is not particularly useful. Deeper, hardware-independent mathematical truths about algorithms are revealed by asymptotic runtime complexity. In this post, we will explore the problem of sorting a list of n numbers using an asymptotic time complexity of O(n log n). Which sorting algorithm has the best asymptotic runtime complexity? The best asymptotic  time and space complexity of sorting   is O(n log n), which means that for any given instance of the problem, it will take less time than the problem has space to solve.  This happens because the height of a heap is constant and so when we add more items to our heap, we make it harder for them all to fit on top of each other.  The num...

  Did You Know? If you write “import this” in Python, then you will see the poem written by Tim Peters, who is one of the major contributors.  You all might have heard about the Python programming language. It is a very easy-to-learn programming language that comes with simple and easy-to-understand syntax.  Writing codes in Python is very easy when we compare it with others. The Python language is being learned by a lot of beginners who are new to the programming world and it is very important for them to start from the basics.  Stick with the guide to start learning the Basics of Python. Why Should You Learn Python? After the commencement of Python, programmers have seen a surge in job opportunities in different fields which includes Data Science, Web Development, Graphics, AI ML, etc.  All of the job fields require high learning of Python and come with a high potential of earning, but it can only be done if you have learned the language very well.  Apart...

  In this article, we will learn  how to reverse a string in C . Also, we will enhance your knowledge on the permutation of strings which contain the same characters.  Using the strrev() function. The strrev() function is used to reverse a string in C and returns the result. This can be useful when you want to reverse an array of characters or if you want to reverse the contents of an array variable. To use this function, call it with your string as a parameter and then pass in an empty array as the second parameter, and hence, the return value will be your reversed text! Here is an example of how to use it: $array = array(‘ABC’, ‘DEF’); $reversed = rrev($array); print_r($reversed); Without using the library function. To reverse a string, you can use the strcpy() function. This function copies the string from the second argument (the one you want to reverse a string in C) to the first argument. The second argument should be a pointer that points at your original string as...
