Hello Dear Developers,

LearnCPlusPlus.org is the ultimate destination to learn how to use the powerful C++ language in easy steps. We truly believe this, and everything we do is geared toward providing you with a quick introduction to programming in C++ and how to compile c++ in windows if you’re a beginner, all the way up to the most robust, modern, and up-to-date techniques for those more experienced with the language or those looking to expand their knowledge with the most up-to-date features, routines, and methodologies.

C++ is a modern answer to your software questions

For those taking those first steps down the golden path of C++, as we said before, we will keep diving into Classes & Objects in the next weeks. One of the most powerful features of C++ is Object-Oriented Programming (OOP), which makes it different from the C programming language by using Classes, Objects, and more. Object-Oriented Programming has many advantages over procedural programming and it is the most characteristic feature of the C++ programming language.

Let’s learn about C++ Constructors

The Constructor in C++ is a function, a method in the class, but it is a ‘special method’ that is automatically called when an object of a class is created. We don’t need to call this function. Whenever a new object of a class is created, the Constructor allows the class to initialize member variables or allocate storage. This is why the name Constructor is given to this special method.

If we dive into Constructors subject, there are different contractor types

  • Default Constructor (This week’s peeks are about these)
  • Copy Constructor
  • Move Constructor (since C++11)
  • Copy Assignment operator
  • Move Assignment operator (since C++11)
  • Destructor

Most of these methods is not only used in classes but also used with struct and union data types, and the Default Constructor in classes is one of these.

What is a C++ Default Constructor?

Default Constructor in C++ is a constructor type in Classes that is called when class is defined with no arguments. It can also be defined with an empty parameter list, or with default arguments provided for every parameter. A type with a public default constructor is Default Constructible;

What is a C++ constructor?

This week we answer the following questions on the LearnCPlusPlus.org website:

  • What is Constructor?
  • How we can declare a constructor inside of a class ?
  • How we can define a constructor outside of a class ?
  • What is deleted default constructor?
  • What is defaulted default constructor?
  • Learn about Defaulted Default Constructor Outside of a Class Definition

Where can I learn about constructors in C++?

We teach you about:

  • Learn Constructors in C++ Classes
  • Learn about Declaration of a Default Constructor Inside of Class Definition
  • Learn Definition of the Default Constructor Outside of a Class Definition
  • Learn about Deleted Default Constructor in C++

  • Learn about Defaulted Default Constructor Outside of a Class Definition

Learn about TURLStream and how it extends the base class constructor C++.

We will continue to Default Constructors in C++ this week. Please keep following our LearnCPlusPlus.org web site for the latest posts and updates. Feel free to comment and share with your colleagues, students, members – knowledge is power and knowledge shared is empowering.
