Member Function is declared as any other variable in C++. Example of Member Function in C++ Let’s understand what a member function is in C++ with the help of an example? C++ # include <iostream> using namespace std; class Employee{ int employee_id; string employee_name; string ...
What is a Virtual Function in C++? In C++, a virtual function is a member function within a base class that’s designed to be overridden in its derived classes. It allows a specific function to be reimplemented in the derived class while preserving a common interface across all derived class...
function_name:This is the name of the function. It is used for identifying and calling functions in the code. Function names must follow the rules of C++ naming conventions, such as not containing spaces and starting with a letter or an underscore. ...
friend return_type class_name::function_name (arguments); // for a member function of another class class intellipaat{ friend int intellipaat_Function(paat); statements; }In this example, friendFunction is declared a friend of the MyClass class and can access its private member, privateData....
A friend function is a non-member function, to make a function a friend of a class, we declare class function with prefixing keyword friend.

See also my question here: What is a call to char() as a function in C++? So, let's recap: : root(sz) in the constructor is like constructing vector<int> root(sz);, which creates sz number of elements in the root vector, each with initial value int(), which is the sy...
data_type = data type (also known as cast operator) to which the expression is to be converted. To understand typecasting, consider this example. float (num)+ 3.5; //num is of int type In this example, float () acts as a conversion function which converts int to float. However, thi...
No function calling ambiguity between overload sets. You can do template specialization with nullptr_t. Code will become more safe, intuitive & expressive. if (ptr == nullptr); rather than if (ptr == 0);. Is NULL in C++ equal to nullptr from C++11?
Introduction to Constructors in C++A constructor in C++ is a special member function responsible for initializing the data members of an object when the same is created. A constructor’s nomenclature closely resembles the class. It has the same name as the class with no return type. Constructor...
