Searching for sub-directories in a given directory is a common task in many applications. In C#, we can use the Directory and DirectoryInfo classes provided by the System.IO namespace to perform this task. In this article, we will explore how to write a C# program to search for sub-directories in a given directory. Method: Using DirectoryInfo.GetDirectories() The simplest way to search for sub-directories in a given directory is by using the DirectoryInfo.GetDirectories() method. This method returns an array of DirectoryInfo objects that represent the directories within a specified directory. Here's how we can use the DirectoryInfo.GetDirectories() method to search for ...

Searching directories and listing files is a common task in many applications. In C#, we can use the Directory and File classes provided by the System.IO namespace to perform these tasks. In this article, we will explore how to write a C# program to search directories and list files. Method: Using Directory.GetFiles() The simplest way to search directories and list files in C# is by using the Directory.GetFiles() method. This method returns an array of strings that represents the paths of all files in a specified directory that match a specified search pattern. Here's how we can use the Directory.GetFiles() ...

In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. The matrix in java is nothing but a multi-dimensional array which represents multiple rows and columns. Here we have given a matrix which contains set of elements and as per the problem statement we have to find largest and smallest element in primary and secondary diagonal of a matrix. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1Given matrix = 21 22 23 24 25 26 27 28 29 ... Read More
In C#, LINQ (Language Integrated Query) is a powerful feature that allows us to perform queries on various data sources, including arrays, lists, and databases. It is an efficient and concise way to manipulate data and has become an essential tool for developers. In this article, we will explore how to use LINQ to reverse a list of cities in C#. Before we dive into the code, let us first understand what LINQ is. LINQ is a set of extensions to the .NET Framework that provides a standard way to query data from different data sources using a common syntax. ... Read More
In programming, there are many situations where we need to reverse a string. One of the most common ways to do this is by using the Reverse() method. However, there are situations where we cannot use this method, and we have to reverse the string using other techniques. In this article, we will explore how to reverse a string in C# without using the Reverse() method. Before we dive into the code, let us first understand what a string is. A string is a sequence of characters that represents text. In C#, a string is a sequence of Unicode characters. ... Read More
C# is a popular object-oriented programming language used to develop Windows applications, web applications, and games. In this article, we will discuss how to write a C# program to read a string and find the sum of all digits present in the string. Step 1: Reading the Input String The first step in this program is to read the input string from the user. We can use the Console.ReadLine() method to read the string from the console. Here is an example − Console.WriteLine("Enter a string:"); string inputString = Console.ReadLine(); Step 2: Finding the Sum of Digits The next step ... Read More
A circle is a closed shape formed by tracing a point that moves in a plane such that its distance from a given point is constant. In this article we will check how to form the equation of circle from given radius and centre. We will be given a circle with point i.e (x, y), radius r and centre i.e (x1, y1). We need to form the equation of circle from given radius and centre. The equation of the circle is given by formula − $$\mathrm{(x\:-\:x1)^2\:+\:(y\:-\:y1)^2\:=\:r^2}$$ Where, (x, y) is a point. (x1, y1) is centre. And r ... Read More
Introduction Memory management is a crucial part of computer systems that deals with managing memory resources. Memory is where computers store data, instructions, and programs while they are being used. Managing memory is important for the computer system to run smoothly. In this article, we will discuss what memory management is, and its benefits and drawbacks. Memory Management Memory management is a crucial task for the operating system, as it is responsible for managing the allocation and release of memory for different applications and processes. The operating system divides memory into different areas and assigns these regions to the applications ... Read More
Introduction Some operating systems use memory ballooning to optimize memory usage in virtualized environments. It entails dynamically reallocating memory resources among virtual machines (VMs) based on their current requirements. In this article, we will explore what is Memory Ballooning, and its advantages and disadvantages in detail. Memory Ballooning Memory ballooning is a technique used in virtualized environments to optimize the use of memory resources. It allows the operating system to reclaim unused memory from one virtual machine and allocate it to another that requires it. This helps to prevent resource waste and improves overall performance. Memory ballooning is achieved through ... Read More
Introduction In computer science and operating systems, memory allocation techniques are used to allocate memory to programs and processes. The mapping of virtual addresses to physical addresses is an important aspect of memory allocation because it allows programs to access the memory they require to run. Mapping Virtual Addresses to Physical Addresses Virtual addresses are used by programs to access memory, while physical addresses are the actual locations in RAM where data is stored.Memory allocation techniques manage the mapping of virtual addresses to physical addresses using different methods. Methods of Mapping Virtual Addresses to Physical Addresses There are three common ... Read More
