Answer :

A constructor is a special member function whose task is to initialize the objects of its class. It is special because its name is same as the class name. The constructor is invoked whenever an object of its associated class is created. It is called constructor because it constructs the value data members of the class.

Syntax:

class_name( )

{

Constructor body

}

Example:

class ABC

{

int a;

public:

ABC( )//constructor declaration

{

a=0;

}

};

void main()

{

ABC x;

}
