Re: [algogeeks] post and pre increment operators
You are wrong, this doesn't depend on the order which is used by printf. In C/C++ order of evaluating function's parameters is undefined. So you may receive different results in different compilers. -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

Re: [algogeeks] post and pre increment operators
@priya, Generally printf evaluation starts from left to right so first a++ using post increments assign the value of 3rd %d to be 2 then a++gets evaluated , now a value is 3 2nd %d takes a value as 3 1st %d takes a value as 3 if it is a preincrement like ++a in the third place the output will be 3,3,3... got it i guess...

Re: [algogeeks] post and pre increment operators
Yeah you might be knowing how the expression evaluators work using stack right. printf also uses the same approach On Sun, Jan 9, 2011 at 11:06 AM, priya mehta priya.mehta...@gmail.comwrote: @kartheek so does it use stack for that?

ok but the output of int a=10,b; b=a++ + ++a; printf(%d,%d,%d,%d,b,a++,a,++a); is 22 13 14 14 howz that then?

Re: [algogeeks] post and pre increment operators
b=(11++)+ (++10)=11+11=22 a=12 in printf the control goes to right first , i.e. ++a , so ++a =(++12), (a becomes 13 but ++a is not printed) then control moves to a but as the next expression pushed in stack is of the same variable so control moves to a++. without printing a a++= 13++, (now a becomes 14) , the control moves now to a=14, the control moves to ++a now as the value of a is changed ++a=14 (it evaluates a from all expressions and then prints) the expressions are popped from stack ( right to left) and printed left to right . as a++=13,a= 14, ++a=14 I hope now things get clearer to you On 9 January 2011 11:16, priya mehta priya.mehta...@gmail.com wrote: ok but the output of int a=10,b; b=a++ + ++a; printf(%d,%d,%d,%d,b,a++,a,++a); is 22 13 14 14 howz that then?
