Answer / amit chauhan
* these are the special member fun" used for automatic
initialization of the object of the class.
* these r defined along with other member fun"of the
class,but the format of the constructor definition is diff.
from the other member fun".
* constructor can take parameters in their parameter list as
needed, called parametrized constructor.
* but they can't return a value,not even void.
* the name of the constructor is same as that of the class.
* constructor r called automatically whenever an object of
the class is created.
* a constructor without any parameter is called default
constructor.
* there is one another type,called copy constructor.compiler
will use the copy constructor whenever you initialize an
instance using values of another instance of same type.

Answer / narayan prajapati
Constructor is What?
Example(Constructing Builings Or in our programing Builing
Programs)
1.It Should Have Same Class Name eg.(Fun)& Function Name eg.
(Fun)And Pass Suitable Parameters
2.Its Function Doesn't Return Value.
3.When Object is Initialize,it Directly Call.
4.constructor Works First & then When main Function work
completed the Destructor Come to work,And Clear the
Previous Data.
5.while Initializing parameters in main function,we Should
take Care Of Constructor Function Parameters eg.(If 2
parameters Are pass in constructor function then is
necessary to pass 2 parameters in main function,if not it
Will Send An Error!)
