Why even use a copy constructor in the first place? Before we explain this problem further, it helps to define a copy constructor: A copy constructor is a constructor that takes only one parameter which is the same exact type as the class in which the copy constructor is defined. For ...
In this article, we will explore various methods for copying vectors in C++. We will delve into standard library functions, user-defined functions, and modern techniques like the copy constructor and the std::vector assignment operator.Use the Iterative Method to Copy a Vector in C++...
Constructor, as the name suggests is used to allocate memory (if required) and construct the objects of a class while destructor is used to do the required clean-up when a class object is destroyed. In this article, we will study the concept of constructors and destructors through working e...

Here is how we would like to use it to make our wrapper that never makes a copy.template <class T> class TextDisplayer { public: explicit TextDisplayer(T&& text) : text_(std::forward<T>(text)) {} private: T text_; };Note: in real code we would choose a more descriptive name ...
