What is the value of k after operation? int k = 5; k += k++ + ++k; why its output depends on compiler?

Answer 1

firstly, k=5
++k , k=6
k++ + ++k, 6+6=12
k+=k++ + ++k, now k++ was activated it made k=7
So finally k = 7+12 = 19

Answer 2

why sololearn rejected that by saying it produces different outputs on different compilers?

Answer 3

Yes, you are right. It can be executed correctly.

Answer 4

bro its high level question in C
or other lang.

Answer 5

Sorry, but answer is 19

Answer 6

"why sololearn rejected that by saying it produces different outputs on different compilers?"

Because in this expression you have only addition, so you can't determine priority used by each compiler?

Answer 7

Sorry bro, you can check on any compiler this code
it will give you answer 19

Answer 8

You, twisted mind Oo

Answer 9

I don't think you encounter this each days, and it's easy to clarify the code to avoid problems, at least with parenthesis, if it isn't by divide your one-line instruction to multi-line ones :P

Answer 10

K = 16, don't ask how? 🎄😊😀

Answer 11

Answer in bluej is 17
