The fread function reads nmemb elements from the given stream to the given array. for each element, fgetc 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 read. It is declared in stdio.h and takes four arguments. The fread […]

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 have explained how we can create a dynamic array in C. But my reader says to write an article to create a vector in C. Basically vector is a dynamic array that has the ability to resize itself automatically when an element add or removed from the vector. A vector

Constructors in C++ are special member functions that initializes newly created object of a class. It invoked automatically at the time of object creation. The name of the C++ constructors has the same name as the class or struct and do not have any return type. If you will not create own constructor then, the

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
