Why this difference ?

[Dileep Krishnan <dileepkrishnan at gmail dot com>]

Sir,
>From the FAQ section of your home page I came to
know that there is little difference between executables
generated by C and C++ compilers for a 'Hello World'
program.
I found that this is exactly the case of gcc-3.4 in my
Debian Linux. The size of the C-executable is 11521
bytes and C++ executable is 13568 bytes.

But the behaviour is quite different in Windows XP.
I have installed gcc-mingw(gcc version 3.4, mingw
version 4.1.1) on my WinXP. I tried the same
'Hello World' programs. I had used 'gcc -o2' &
'g++ -o2' for compiling, just as you had mentioned
in the FAQ. This time the size of the exe's are drastically
different. The C-exe is 15,661 bytes & the C++ exe is
474,849 bytes.

The C++ exe is 30 times the size of the C exe.
Could you please tell me why this happens and what I
should do about it? Is there anything I have missed
to do?

The C source code is as follows:
**********************************
#include <stdio.h>

int main(int argc, char *argv[])
{
  printf("Hai!!!\n");
  return 0;
}
**********************************

The C++ source code is as follows:
*************************************
#include <iostream>
using namespace std;

int main(int argc, char *argv[])
{
  cout << "Hai!!!!" << endl;
  return 0;
}
*************************************

Thanking You,
Regards,
Dileep
