Pls why is the answer 16

Question

x = 8;
y = 7;
x++(x changes to 9)
x += y--(therefore x = 9 + 6)
so pls can someone tell me how the answer is 16 tho :(
what did i miss out

Answer 1

y is 7, not 6.

Answer 2

You called y before decrementing.
Your answer could give 15 if your last statement was:
x += --y

Answer 3

y-- is post decrement so first it will assign the value then Decrement by 1. So here

y-- will be 7 and after assigning y will be 6

x = x + y-- = 9 + 7 = 16

and finally y = 6

Answer 4

But y was decremented🤔

Answer 5

x = 8;
y = 7;
x++ // x=9
x += y--//x=9+7 -> x=16

Answer 6

Oh thanks ya'll i see it now
