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

Sir,please help me out with the code of this question. Write an interactive C program that will encode or decode multiple lines of text. Store the encoded text within a data file, so that it can be retrieved and decoded at any time. The program should include the following features: (a) Enter text from the keyboard, encode the text and store the encoded text in a data file. (b) Retrieve the encoded text and display it in its encoded form. (c) Retrieve the encoded text, decode it and then display the decoded text. (d) End the computation. Test the program using several lines of text of your choice.
