C++ problem

Hello Everybody I tried this code. Code gives 0 warning and 0 errors. I tested under Turbo C++ environment. My Question is How Constructor of all classes is called without creating an object? I know once constructor of class C is called it is automatically called upper class’s constructor. Basic question is how Constructor of class C is called with creating an object of that class?

**********CODE**********

#include<iostreams.h>

#include<conio.h>

#include<stdio.h>

class A

{

public :

A()

{

cout<<"A\n";

}

};

class B : public A

{

public :

B()

{

cout<<"B\n";

}

};

class C : public B

{

public :

C()

{

cout<<"C\n";

}

};

void main()

{

clrscr();

C();

getch();

}

FB chat as Text Message on your Mobile

Many times you may see my chat status is available. But mostly I m off-line. Your all IM send on my phone. So please understand this fact, if I am not replied on chat...

Now don't ask hows this possible. I m giving the answer.
Use yahoo messenger and register your mobile on it. And register your mobile for yahoo mobile contact. Then import all your facebook contact into that yahoo account. And done. You receive a text message from +5824119 or else.

*Tip :
1. This feature is available only for Yahoo India Messenger 11
2. You receive only 3 messages from a single contact at a single day...
