Base class constructor called first next it wil call Derived
class constructor

Answer / sangeetha

"C++ classes honor their parents by calling their parents
constructor before they call their own." The base class
constructor will be called before the derived class
constructor. This makes sense because it guarantees that
the base class is properly constructed when the constructor
for the derived class is executed. This allows you to use
some of the data from the base class during construction of
the derived class.

Answer / prajeesh

#include <iostream>
using namespace std;

class BaseClass {
public:
BaseClass() { cout << "Constructing base portion\n"; }
~BaseClass() { cout << "Destructing base portion\n"; }
};

class DerivedClass: public BaseClass {
public:
DerivedClass() { cout << "Constructing derived
portion\n"; }
~DerivedClass() { cout << "Destructing derived
portion\n"; }
};

int main()
{
DerivedClass ob;

// do nothing but construct and destruct ob

return 0;
}
Constructing base portion
Constructing derived
Destructing derived
Destructing base portion

Answer / nathusingh

If both the base and derived class have constructors then
first of all constructor of the Base Class (Parent class)
will be invoked and then subsequently the constructor of
the derived class will be called.Whereas in case of
Destructors,destructor of the derived is called so as to
destroy the object child object and then base class
destructor is called. In Case of Creation ( constructors)
Parents(Base Class) are honored first while in case of
destruction (destrcutors) children( Derived class) are made
the victim :)

Answer / harsha

First Constructor of base class will be invoked and then the
constructor of derived will be invoked ........

For example
Using System;
class Base

public Base()
{
Console.WriteLine("Base Class");
}
}
class Derived:Base
{
public Derived()
{
Console.WriteLine("Derived Class");
}
static void Main(string[] args)
{
Derived d=new Derived();
}
}

class DerivedClass: public BaseClass {
public:
DerivedClass() { cout << "Constructing derived portion\n"; }
~DerivedClass() { cout << "Destructing derived portion\n"; }
};

int main()
{
DerivedClass ob;

// do nothing but construct and destruct ob
