Hello World.. 
 "Hello World.." I still remember that phrase when it was heard for the first time, when uttered by our faculty for C programming (lets call him Mr. C). At that time I was wondering why the hell is he using this phrase. All programmers use it for the first time , when they learn some prog.language to write that 'simple program'(well, it looked like hieroglyphics for the whole class, (exceptions overruled..) ) and being a programmer, Mr. C used it too..

I use this phrase while stepping into a new technology.. a new world..
