22 21 21 20 THIS WILL THE OUTPUT..
this is merely an STACK operation.... here we have 4
parameters.. so the four parameters will be pushed inside
the stack one by one... as
TOP : k
++k
k++
BOTTOM : k
so the expressions will be evaluated from the top.. and thus
the answer....
thank u

Answer / mohamed ali
THE ANSWER IS
20 20 22 22
YOU HAVE THE 1ST 20 AS IT'S THE INITIAL VALUE
THEN YOU HAVE K++ .... HERE WE HAVE THE SAME VALUE OF K THEN
IT WILL BE INCREMENTED BY ONE .... SO YOU HAVE THE 2ND 20
AND THEN K WILL BE 21
THE THIRD YOU HAVE ++K .... WHICH MEANS THAT YOU WILL
INCREMENT THEN TYPE THE VALUE AND SINCE YOU HAVE NOW K=21
FROM PREVIOUS STEP (K++) SO THIS VALUE WILL BE INCREMENTED
BY ONE (K = 22 ) SO YOU HAVE THE THIRD VALUE 22
THEN YOU HAVE A SINGLE K WITH NO OPERATIONS SO ANOTHER 22
IF SOMEONE SEES THAT I'M WRONG PLZ CORRECT MY VIEW
THANKS

Answer / rajadurai thangaraj
22 21 22 22
stack execution:-
4 ->printf k now k=22
3 ->printf 21 k=k+1 now k=22, k of 1&2 also 22
2 ->k=k+1 printf k now k=21, k of 1 also 21
1 ->printf k now k=20

Answer / anand
The answer should be 22212120
Arguments passed to the printf statement would get executed
from the right to left..
1. k = 20
2. ++k = 21 (Pre Increment)
3. k++ = 21 (Post Increment(k value now is 22))
4. k = 22
Thus the output : 22212120
