7 Things You Need To Know on LearnCPlusPlus This Week

7 things you need to know on learncplusplus this week

Hello C++ Developers,

LearnCPlusPlus.org is the ultimate destination to learn how to use the powerful C++ language in easy steps. We believe this and everything we do is aimed at giving you a rapid introduction to programming in C++ if you’re a beginner, all the way to the most robust, modern, and latest techniques for those more experienced with the language or for those who are perhaps wanting to expand their knowledge with the most up-to-date features, routines, and methodologies.

This week we have a few more posts about Default Constructors; we will keep diving into Classes & Objects in the coming weeks. We show how to download and set up popular Embarcadero C++ IDE easily. For professionals, we have two CppCon Videos that we pick. As we mentioned before, 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 (Last week and 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 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;

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

  • What is Implicitly Declared Default Constructor?
  • What means Deleted Implicitly Declared Default Constructor?
  • What is Trivial Default Constructor?
  • How can we set up Dev-C++?
