[PDF] parameterized constructor in c++

How to pass parameters to a constructor?

When only the constructor of the derived class requires one or more arguments, you use the standard parameterized constructor syntax. To pass arguments to a constructor in a base class, use an expanded form of the derived class' constructor declaration, which passes arguments along to one or more base class constructors.

How to create an object with the constructor with parameter?

To create a parameterized constructor, it is needed to just add parameters as a value to the object as the way we pass a value to a function. Somewhat similar scenario we do by passing the parametrized values to the object created with the class. Parameters are used to initialize the objects which are defined in the constructor’s body.

What does a default constructor mean in C#?

In both Java and C#, a "default constructor" refers to a nullary constructor that is automatically generated by the compiler if no constructors have been defined for the class. The default constructor implicitly calls the superclass's nullary constructor, then executes an empty body.

What is the use of a private constructor in C#?

In c#, Private Constructor is a special instance constructor, and it is useful in classes that contain only static members. If a class contains one or more private constructors and no public constructors, then the other classes are not allowed to create an instance for that particular class except nested classes.
