grow up man!! once u popped up a question on me..nd on the next chance u gave an ans...as far as i think knowledge is not only about "SOMEONE SAID" then "U GET". U need to find it out urself what goes on in SMPS?? Be practical!! Be confident!! Don't give HAZY ans.. If u dnt get then say X=NULL nd if u get then give X=yyyyyy...if a bowler is off spinner then who says that he can't throw googly..itz batsman whose greatness judges whether he will be able to face every ball or not...i hope admin agrees with me!!
