In C++, visibility modes refer to the accessibility of class members (such as variables and functions) from different parts of a program. C++ provides three visibility modes: public, private, and protected. These modes control the access levels of class members concerning the outside world and derived classes. Public: Members declared as public are accessible from … Read more
In C++, inheritance is a fundamental concept of object-oriented programming (OOP) that allows you to create a new class based on an existing class, known as the base or parent class. The new class is called the derived or child class. Inheritance facilitates code reuse and supports the creation of a hierarchy of classes. There … Read more
In C++, classes and objects are fundamental concepts that support object-oriented programming (OOP). Here’s a brief overview of classes and objects in C++: Classes: In C++, a class is a user-defined data type that allows you to encapsulate data members and member functions into a single unit. Classes are the building blocks of object-oriented programming … Read more
In C++, the “this” pointer is a keyword that represents a pointer to the instance of the class to which the member function belongs. It is implicitly passed as a hidden argument to all member function calls. Here’s a basic explanation of the “this” pointer: Types of this pointer Pointer to the Current Object: Inside … Read more
In C++, enumeration (enum) is a user-defined data type that consists of named integral constants. Enums are useful for creating more readable and self-explanatory code by assigning names to numeric values. Here’s a basic example of how to use enums in C++: #include <iostream.h> // Define an enumeration named Color enum Color { RED, … Read more
Certainly! C++ is a general-purpose programming language that was created as an extension of the C programming language. It was developed by Bjarne Stroustrup(Bjarne Stroustrup is a Danish computer scientist who is best known for his creation of the C++ programming language.) at Bell Labs in the early 1980s. C++ is known for its efficiency, … Read more
Abstraction is one of the fundamental principles of object-oriented programming (OOP), and it plays a crucial role in C++. Abstraction involves simplifying complex systems by modeling classes based on the essential features they possess while hiding unnecessary details. In C++, abstraction is implemented through classes and interfaces. Here are some key concepts related to abstraction … Read more
a constructor is a special member function of a class that is used to initialize the objects of that class.
In C++, a destructor is a special member function of a class that is automatically called when an object of that class goes out of scope or is explicitly destroyed. It is used to clean up any resources or perform any necessary actions before the object is destroyed. The syntax for a destructor in C++ … Read more
In C++, a friend function is a function that is granted access to the private and protected members of a class. It can be declared inside the class, but it is not a member of that class. A friend function can be useful when you need to allow a function external to the class to … Read more
