Chetan,
you're right, the -o option names the output file.
However, the -o2 option does NOT name the output file to be "2" but
sets the optimisation level to 2.
This is a very unfortunate but still vivid example of command-line
options not conforming to any standards. Very confusing indeed. It
took me quite some time to understand this hysteric... eh, historic
nonsense.
Regards,
Nico

Hi Nico,
I tried the -o2 option, but no change in the size of final exe.
I tried on cygwin ang mingw compilers.
Following are the output:

$ cat hw.cpp
#include <iostream>
int main()
{
std::cout<<"Hello World!"<<std::endl;
return 0;
}

$ g++ hw.cpp

$ ls -l a.exe

$ ls -l a.exe

On mingw:
