Learn about 10 Difference between structure and class in C++
Greetings, fellow C++ enthusiasts! If you’re new to the world of programming, you may have come across the terms “structure” and “class” in C++ and wondered what sets them apart. Fear not! In this article, we’ll break it down in simple terms to help you understand the key differences between these two concepts. So let’s dive in and demystify this topic in a way that’s easy to grasp!
10 Difference between structure and class in C++
Hey there! Let’s dive into the 10 difference between structure and class in C++, shall we? Brace yourself for some coding wisdom!
Declaration and Initialization: In C++, members of a structure are declared and initialized with the default access specifier as ‘public’, while members of a class are declared and initialized with the default access specifier as ‘private’.
Inheritance: Inheritance in classes can be public, protected, or private, allowing for various levels of accessibility, while in structures, the inheritance is always public.
Data Encapsulation: Classes provide better data encapsulation as members are private by default, and can be accessed only through member functions, whereas structures have all members public by default, allowing direct access to data.
Member Functions: Classes can have member functions, including constructors and destructors, while structures can only have member variables and cannot contain member functions.
Constructor and Destructor: Classes can have multiple constructors and destructors, while structures can only have a default constructor and destructor.
Static Members: Classes can have static members (variables and functions) that are shared by all objects, while structures cannot have static members.
Default Accessibility: In classes, members declared without any access specifier are private by default, while in structures, members declared without any access specifier are public by default.
Object Creation: Objects of a class must be created using the ‘new’ keyword, whereas objects of a structure can be created without using ‘new’.
Size: The size of an object of a class is generally larger due to additional overhead of virtual function tables, while the size of an object of a structure is generally smaller.
Typecasting: Typecasting between objects of different classes is possible using concepts like polymorphism, while typecasting between objects of different structures is not supported.
So, there you have it! Ten key difference between structures and classes in C++. Hope this gives you a clear picture of the distinctions. Happy coding!
