Answer 1

I haven't tested it, maybe you find some inspiration here:

https://www.geeksforgeeks.org/multiply-two-numbers-without-using-multiply-division-bitwise-operators-and-no-loops/

Now that you have written your own add-method, you can replace the + by that

Answer 2

What is it then? A challenge? You can put it in a challenge thread...

If there is an issue with the code, can you please specify what isn't working? I get a compiler warning if I don't un-comment line 42, for example.

Answer 3

That is what is am saying: I get a compiler warning due to line 41

Answer 4

Try to run the code on sololearn playground. It a warning about "unused variable"

Answer 5

You ask a pseudo-question: you answer your own question immediately, mark your own answer as best and upvote it?

Maybe you rather want to advertise your code in an advertising thread?

Answer 6

Lisa you may be true but it is not sharing have you opened or understand me what is shown on the code.

Answer 7

Lisa you dont need uncomment any line only you should enter two number

Answer 8

You are true that i havent pay attention to this

But Lisa warning is not means the code is warking worse but if you also use unused var like me , it is not wrong

But if you pay another attention to this code it returns addition of two numbs without + operand

The mens of my checking my best ans to this quest is that the CODE IS ADDING WHITOUT + opr
I want you help like this but not add
BUT logical multiplication

Answer 9

Jacob Tracey i have banchmarked my code that you are really true

Test Count: 1 234 567 890 times

Result:
(+) operand =>> 12s
My func Add =>> 1m 43s

my Add func is 9 times slower than (+) operand

Answer 10

But i dont warning on my compiler

What kind of warning is it Lisa

Answer 11

Really good that i have tested Lisa

Answer 12

Jacob Tracey not agree
