in first iteration x :5 y: 5 condition x >0 & & y <6 // true second iteration x: 4 y: 9 condition x >0 & & y<6 // false because 9 >6

your while loop executes twice. first 6 is decremented by 1, then added to y (which is 0). y now equals 5. the second time the loop goes through, it adds 4 to y and stops because y is now greater than 6. y is now 9, your loop stops and writes 9

First condition X-- (6-1=5) Y+x (5+0=5) Second condition X--(5-1=4) Y+x(5+4=9) So output will be 9
