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

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

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
