what is Constucter?

[ursimrankhanna]

plz reply the my question...
Thank you.....

[jurwanwall]

class Rectangle{
int l, b;
float p, q;
public Rectangle(int x, int y){
l = x;
b = y;
}
public int first(){
return(l * b);
}
public Rectangle(int x){
l = x;
b = x;
}
public int second(){
return(l * b);
}
public Rectangle(float x){
p = x;
q = x;
}
public float third(){
return(p * q);
}
public Rectangle(float x, float y){
p = x;
q = y;
}
public float fourth(){
return(p * q);
}
}

HI,
Constructor is function which describe from the class name.we use the Constructor when we do not describe the class object in main method.

[deveshraigniit]

Constructor:-
Constructor is like a class function if we be called the without define the object of the class then we use the constructor.

Syntax:-

class Add
{
public Add()
{
int a=20;
int b=30;
int result= a+b;
console.WriteLine("The Value is"+result);
}
public static void main(String [] args)
{
}
}

It is a great a clear answer, i learn it too

some times we can say that constructor is a class but its not exactly a class.but its having the same name of the class.it automatically called at the time of execution.

[jenny3103]

onstructor are used for initialization of member variables.Constructor are automatically invoked when the object is created.Constructor doesn't have any return type not even void.Constructor have the same name as the class name.We can't call the constructor explicitly.

[tylerlongtw]

A constructor is just like a function but it has the same name as the class does, and is called whenever the object of that class is being created.

[amkeabhi123]

constructor is method of class when we create the object then create the automatically constructor.

[Loan2day]

When a object is created, the variable of the objects must be initialized. Initialization of variable of object is done automatically when the object is created .The object is initialized at the time of creation of it by means of a special function. This special function is known as constructor. It is called as constructor because it constructs the value of data member of class

[vikramrandhawa]

A copy constructor is a special constructor in the C++ programming language creating a new object as a copy of an existing object.Copying of objects is achieved by the use of a copy constructor and an assignment operator. A copy constructor has as its first parameter a reference to its own class type. It can have more arguments, but the rest must have default values associated with them

[gaurav467]

Constructor is a default member function available with a
class.

[sandeep552]

Constructor:-
A particular member function whose task is to initialize the object of class.

[lucasyesher]

However constructor name and class name are same and helpful to initialized the object of the class at the static scenario.

[sonu sing]

In object-oriented programming, a constructor (sometimes shortened to ctor) in a class is a special type of subroutine called at the creation of an object....

[maxsamuel]

When a object is developed, the different of the elements must be initialized. Initialization of different of product is done immediately when the product is developed .The product is initialized at a lot of length of technology of it through a exclusive work. This exclusive work is known as constructor. It is known as as constructor because it constructs the value of details individual of class
