fwrite in C writes nmemb elements from the given array to the output stream. for each object fputc is called size times (count of bytes for a single element) and file position indicator for the stream is advanced by the number of characters written. It is declared in stdio.h and takes four arguments. The fwrite […]

Sometimes we require persistent data in our C program, in that situation knowledge of file handling in C is very helpful. So you should have the basic knowledge of file handling in C. Basically, file represents a sequence of bytes that store in the disk permanently. Previously, I had worked on a restaurant application( Vx520

We use the const reference in C++ when we want to refer to a const type. It prevents changing the bounded object and also refers to a constant value (like 6, 27, 2.4 ..etc). In my previous article, I have explained the reference in detail if you had not read it, please check this link,

C++ provides the pointer and reference to refer the object indirectly. But it is our choice to use the pointer or reference in our code for accessing the object indirectly. But C++ insist to use the reference but it is up to you and your requirement. Basically, reference defines an alternative name for an object

In my previous article, I explained how to create a dynamic array in C. After reading the post, Many readers requested a guide on implementing a vector in C. A vector is essentially a dynamic array that stores a collection of elements same type in a contiguous memory. It has the ability to resize itself

Constructors in C++ are special member functions that are automatically called when a class object is created. They are used to initialize the class objects. The constructor’s name is the same as the class name, and it does not have a return type. If you do not create your own constructor, then the compiler creates

Sometimes we require to communicate with an external device like a printer, microcontroller board or any serial device using the serial port of a windows machine. There is a lot of serial application available like Hercules, HyperTerminal, Docklight, ..etc. We can use any one of them for serial communication but sometimes we require to create our

I have worked on the windows printer driver, where I have to install the port monitor silently without user interaction. It is a user-mode DLL which responsible for providing a communications path between the user-mode print spooler and the kernel-mode port drivers that access I/O port hardware. You can also check the below article, How

In this article, I will explain the local static and global variables in C. Basically variable defines a location name where you can put value and you can use these values whenever required in the program. You can also read below Articles, 1. Introduction of data types 2. Variable in C 3. Storage Class introduction

Before start discussing on “Insert a node in the doubly linked list?” First, I will put a light on a “singly linked list”, A singly linked list is a collection of nodes in which a node consists of a data part and pointer part. The data part store the value (maybe integer, character, and floating
