Answer
$a=345$
$b=89$
Work Step by Step
After calling the CodeWrite function the control will enter the if block because the condition a>0 and b>0 is true, then the given mathematical operation will be performed and we have:
$a=78,b=89$
$a=78+89=167$
$a=167+89=256$
$a=256+89=345$
So in the end we will have:
$a=345$
$b=89$
