Well Guys, Jst to through some light on last Query.i.e y=++x + (++x + ++x) ;
if you check the current activation record there is space allocated for only one variable that goes on changing till you dont violate the pint Rule. So you both are correct.. it will print 18 and yeah the value is computed as (++x + ++x ) and than + to ++x.. its only cox all the variables are same x which will get evaluated finally as 6 before final addition. Please feel free to comment on my understanding.. ;) Prem On Mon, Jul 25, 2011 at 3:50 PM, Arun Vishwanathan <aaron.nar...@gmail.com>wrote: > well I dint expect that value for y:)!! thot it wud be 16 again..but since > u ask me to guess i wud say that as we go left to right , the first > preincrement causes x to be 4 and the ones within the bracket cos it to be 5 > and then 6:Now first addition within the braces is 6+6=12 and then this is > added to 6(since x was already incremented earlier) to be 18..hey it is a > totally wild guess > what is the right approach here?:) > > > > On Mon, Jul 25, 2011 at 12:10 PM, sagar pareek <sagarpar...@gmail.com>wrote: > >> yeah u are right :) >> try this one:- >> >> x=3; >> y=++x + (++x + ++x); >> >> answer is y=18 guess why ?
