In mathematics, the divisibility rule of 5 states that if the number ends with 0 or 5 then it will divisible by 5. There is another way to identify the divisibility rule of 5, if the remainder comes to 0 it returns the number is divisible by 5. The mod(%) operator is normally used in programming when it comes to divisibility. Following are some examples which helps you to understand the divibility rule of 5 − Given number is 525, the number ends with 5 and it is divisible by 5. Given number is 7050, the number ends with ... Read More
In C, sorting arrays is a common task, and one of the functions that help with sorting is qsort(). To sort the array, qsort() needs a comparator function to decide how to compare two elements. Without this function, qsort() wouldn't know how to order the data. The task here is to understand how to write and use a comparator function with qsort() to sort arrays in different orders. For example, consider this array of integers: arr[] = {5, 2, 9, 1, 5, 6} We want to sort this array in ascending or descending order. The comparator function tells qsort() ... Read More
A simple calculator allows the user to perform basic math operations like addition, subtraction, multiplication, and division . The user inputs two numbers and selects an operation. For example, if the user enters 4 and 3, then selects the "+" operation, the calculator will perform addition and output the result, 7. Similarly, if the user selects "-", the program will perform subtraction (4 - 3 = 1), and so on. In C++, this can be done using conditional statements and basic math operators. In this article, we will show you how to write a simple calculator program in ... Read More
Creating a folder or directory on your computer is an important task in programming. A directory is like a container that helps store and organize files. In C and C++, you often need to create directories to store data, logs, or configuration files. Creating directories makes file management easier. For example, if your program needs to store logs, it should check if a "logs" folder exists. If not, it can create the folder automatically, so you don't have to do it manually. In this article, we'll show you how to create a directory in C or C++. Creating Directories ... Read More
Reversing an array means changing the order of its elements so that the first element becomes the last, the second becomes the second last, and so on. This operation is commonly used in applications such as data manipulation or algorithms that require elements to be in reverse order. For example, consider an array of integers: arr[] = {1, 2, 3, 4, 5} When the array is reversed, the first element (1) moves to the last position, the second element (2) becomes the second last, and so on. The reversed array will be: arr[] = {5, 4, 3, 2, 1} ... Read More
Vectors are similar to the dynamic arrays but vectors can resize. They are sequence containers that can change their size according to the insertion or deletion of elements. Containers are the objects which holds the data of same type. Vectors may allocate some extra storage for the future growth of elements in the vector. Its elements are stored in the contiguous memory. The data is entered at the end of vector. In this article, we will show you how to print the contents of a vector in C++. Example Scenario: std::vector vec = {10, 20, 30, 40, 50}; You ... Read More
In C++, one common task is to find the largest number in an array. An array is just a collection of values, and sometimes we need to find the highest value in that collection. For example, consider the array: int arr[] = {11, 13, 21, 45, 8}; In this case, the largest element is 45. Similarly, for the array: int arr[] = {1, 9, 2, 5, 7}; The largest number is 9. In this article, we will show you how to find the largest number in an array using different methods in C++, including some built-in features ... Read More
What is File Carving? File Carving is a popular way to get files back from computer memory by using details about their content and structure instead of the file system. This method is very important for digital forensics investigations because it lets you get back files by looking at their text and structure. Getting structured information from raw data based on format-specific properties found in the structured data is what this broad term refers to. The Problem of Destroyed or Deleted Data There are several reasons why files might get deleted. Any of these things can happen by mistake, as ... Read More
In this article, we will learn about Java API documentation generators. Java API documentation generators automate the process of creating structured and readable documentation for Java projects, making it easier for developers to understand and use APIs. What is a Java API Documentation Generator? A Java API documentation generator is a tool that analyzes Java source code and generates documentation in a structured format, typically HTML, XML, or Markdown. These tools extract comments and annotations from the code and transform them into comprehensive references for developers. Different Java API Documentation Generators The Following are Popular Java API documentation generators − ... Read More
In this article, we will learn to add a new row to a table using jQuery. jQuery, a fast and lightweight JavaScript library, in web development, dynamically adding or removing rows from a table is a common requirement, especially when dealing with forms or data entry interfaces. Use CasesThis functionality is particularly useful in scenarios such as − Creating dynamic forms where users can add multiple entries (e.g., adding multiple email addresses, phone numbers, or product details). Building data entry interfaces where the number of rows is not fixed. ... Read More
