Please help me !
The Correct Answer Is : 12;
Buttttttt !!!
I Don't know Why not 48 Or 60 :/ .
" ++i will increment the value of i, and then return the incremented value. "
f=1 i=2
--First Loop
i (in the while) =2 , original i = 3 because ++i;
f = 3 because 1*3 = 3;
--Second Loop
i (in the while) = 3, original i = 4 because ++i;
f = 12 because 3*4 = 12;
--third Loop
i (in the while) = 4, original i = 5 because ++i;
f = 60 because 12*5 = 60;
Whyyyyyyyyyyyyyyyyyyyyyyyy The Answer is 12 ????????!
I will kill myself if I do not know why ! :\(

Answer 1

the I is pre incremented so it's value before the condition is 3.
1 × 3;
system.out.println(f); f = 3.
now it would loop again this time i would be 4
4 x 3;
system.out.println(f) = 12
for the last time I was pre incremented so I became 5 and hence the condition became false so the loop stopped.
hope this helps

Answer 2

I hope that now you dont kill yourself 😒😒😒

Answer 3

Thanks for All <3
I Will No Kill My Self sorry :0
OK this is correct ?
--First Loop
i (in the while) =2 , original i = 3 because ++i;
f = 3 because 1*3 = 3;
--Second Loop
i (in the while) = 3, original i = 4 because ++i;
f = 12 because 3*4 = 12;
--third Loop
i (in the while) = 4, original i = 5 because ++i;
f = 60 because 12*5 = 60;

Answer 4

Yousef10 that would be wrong because when i turns 5 the loop breaks
