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 / manish
Constructor is a special type member function of class,it is
special becoz its name is same as its class name in wich it

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!)

If P is the population on the first day of the year, B is the birth rate, and D is the death rate, the estimated population at the end of the year is given by the formula: The population growth rate is given by the formula: B – D Write a program that prompts the user to enter the starting population, birth and death rates, and n, the number of years. The program should then calculate and print the estimated population after n years. Your program must have at least the following functions: 1. growthRate: This function takes its parameters the birth and death rates, and it returns the population growth rate. 2. estimatedPopulation: This function takes its parameters the current population, population growth rate, and n, the number of years. It returns the estimated population after n years Your program should not accept a negative birth rate, negative death rate, or a population less than 2. please answer my question ....
