Answer / vignesh1988i

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

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
