Answer / robin
different compiler gives different ans..
this is for tc
but its true it work as stack
last in first out
value of k is store in stack
1. k = 20
2. ++k = 21 (Pre Increment )
3. k++ = 21 (Post Increment(k value now is 22))
4. k = 22
As 22 is last it is printed 1st.........

Answer / dasari prasad
Output is 22 21 21 22
Because n printf evaluation starts from last parameter
because of STACK.. so calculate k value from last i.e k=20
and ++k=21 ,k++=21(post incre),k=22.

Answer / puja
THE ANSWER WILL BE
20 20 22 22
BECAUSE THE FIRST VALUE IS K=20 THEN IT WILL BE THE SAME
20 DUE TO K++, NOW THE VALUE WILL BE INCREMENTED & WILL BE
21, THEN ++K, MEANS THE VALUE WILL BE +1 THEN IT WILL BE 22
& LAST K WILL BE SAME 22.
