An instance constructor is a method whose task is to create an instance of a class. A constructor is a member function whose task is to initialize the objects of its class, in other words it is a method of a class that executes when the class's objects are created. It is called a c...
In this blog, I will explain the constructor in C#. A constructor is a special function of the class that is automatically invoked whenever an instance of the class or struct is created. The constructor function initializes the class object. The constructor of a class must have the same na...

A constructor in C++ is a special 'MEMBER FUNCTION' having the same name as that of its class whichis used to initialize some valid values to the data members of an object. ... It is because the constructor is automatically called by the compiler and it is normally used to INITIALIZE VA...

A constructor is similar to a function. It has a name, a parameter list, and a function body. As we can see in the example below, the meaning of an initializer is up to the constructor:string s("my string"); // initialize s to the character string "my string" vector<int> v(100...

In the lesson, you mentioned that "A constructor is a special member function that is automatically called after a non-aggregate class type object is created." If I understand it correctly, when we define a class variable(e.g. Employee a{"name"};) or create a temporary class object(e....
