➢ Constructors can have any type of arguments except its own class type But the constructor can accept a reference to its own class type object as a parameter
m constructors and distructors
The above defined constructor takes two arguments one int and other float to initialize instance members roll and marks for the newly created object and therefore it is called parameterized constructor

We can write a constructor in C++ which can accept parameters for its invocation. Such constructor that can take the arguments are called parameterized

Constructor and Destructor Every class has the following special methods: • Constructor: Called right AFTER new objects are created in memory • Destructor: Called right BEFORE an object is deleted from memory The compiler automatically generates default versions but you can override them
Parameterized constructors- constructors with parameters Used for initializing data members e g Circle(float x) {r =x;} In main function Circle c(3 5); Copy constructors- used when one object of the class initializes other object It takes reference to an object of the same class as an argument e g Circle (Circle &x) { r=x r;}
- Constructor is automatically called for initialization - Where an object goes out-of-scope (e g end of a method) it [s destructor is automatically called Also called when you delete an object - The object is then responsible for releasing its own resources This is C++s way of a more memory safe object management
Types of Constructor Default Constructor-: A constructor that accepts no parameters is known as default constructor If no constructor is defined then the compiler supplies a default constructor student :: student() { rollno=0; } Parameterized Constructor -: A constructor that receives arguments/parameters is called parameterized constructor
Parameterized Constructors: A constructor that takes one or more arguments is called parameterized constructor Using this constructor it is possible to initialize different objects with different values Parameterized constructors are also invoked automatically whenever objects with arguments are created
1 Whether derived class's default constructor is called or parameterised is called base class's default constructor is always called inside them 2 To call base class's parameterised constructor inside derived class's parameterised constructo we must mention it explicitly while declaring derived class's parameterized constructor
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.
