This section tells you how to prevent objects from being copied (hidden and cannot be called by someone else)Two methods:1. Declaring a copy constructor as private and declaring a function without defining it#include #includeclassDummy { Public:

The most important feature of C programs is that all programs are assembled using functions . Main () is called the main function , which is the entry for all programs to run. The rest of the functions are either a parameter or no parameter, which
