Templates in C++ are the powerful feature that allows us to write generic programs (generic classes and generic functions). A single class or function is created to work with different data types using templates. We pass the data types in …
There are private and protected members in a class that is inaccessible from outside of the class, constituting one of the concepts of object-oriented programming i.e. data hiding. However, these rules can be broken by a friend function. A function …
In C++, this is a keyword that refers to the current instance of a class and this pointer holds the address or points to the current object of the class. Also, only the member functions have this pointer. Members like …
Inheritance is one of the most important concepts of object-oriented programming. In C++, inheritance is the process of deriving the properties and behaviors of one class to another class. It is like a child and parent where the child possesses …
Encapsulation is defined as the wrapping up of data(variable) under a single unit. Encapsulation is an important concept of OOP in C++ that binds data and functions inside a class together that manipulate them. Data encapsulation leads to the important …
The interface is implemented using an abstract class in C++, hence the word interface and abstract class are used interchangeably. Abstraction classes are the way to achieve abstraction and abstraction is a technique in programming to hide the internal details …
Data abstraction is the process of hiding the details but only displaying the relevant information to the users. This is one of the main advantages of using abstraction. It is a programming way or a technique through which we can …
Virtual function in C++ is a member function in the base class that we redefined in a derived class. With the use of a virtual function, we ensure that the function is overridden. A virtual function lets the compiler know …
Function overriding allows us to define a function at a derived class that is already present in a base class. And that base is said to be overridden. Both derived and base class has the member function with the same …
C++ allows us to overload methods, constructor and indexed properties. The function or operator define with the same name but with different types of parameters s called overloading. C++ has two types of overloading and they are: Function overloading Operator …
