See the difference (BigInt in C++ and Python)

Question

Rei: To clarify on OP's behalf: Python supports int values of arbitrary size, C++ does not. This is because Python focuses on achieving results quickly, while C++ primes in runtime performance, letting you decide the optimal structure to deal with BigInt. This thread is not an attack on C++. There are also well-written, ready-to-use C++ BigInt libraries online, e.g.

Answer 1

Congratulations, you made me write code.

Answer 2

Sorry, but your C++ code is just overkill. You can do the same calculation in C++ with only 1 line of code and thereby reach a sufficient precision, too:

Answer 3

In programmer performance, Python is superior. In runtime performance C++ is superior.
So the tool of choice for code that only needs to run occasionally is Python. When code needs to run often or runs on a battery powered device, you might want to consider C++.

Answer 4

Yes, you can easily calculate 40 numbers more. That's because Python doesn't have a native variable limit like C++ does. The limit has a reason though. C++ and Python are different languages with different strenghts used for different purposes, so there's no point in badmouthing a language because of something it wasn't built for. Such integer precision doesn't have any practical use in C++ applications and I can assure you that nobody read past the 10th number. You will never write 60 lines to get some extra precision in a calculation and you'll still get a good enough result.
Furthermore, C++ calculates 94 Fibonacci numbers way faster than Python does.
I see your point, but your statement is very misleading.

Answer 5

Chris
totally my post has joking aspect , i want show a small limit can make the code too long
And about function , it's very simple , i will write how it works in next few days

Answer 6

Chris
& another thing
It's not just 30 line code to calculate 40 another numbers that as you said nobody cares about that
It's good training for beginners and for my future project 😉

Answer 7

Hatsy Rei
awesome 👍

Answer 8

wd00009
thank you 😄❤

Answer 9

The thing is, you're nowhere explicitely telling that your statement is about the length of the numbers you're calculating.
You're linking two codes called "Fibonacci series", saying that the C++ one is 60 times longer, and that's it. There's no mention about a joking aspect or what you are actually trying to achieve here.
Yes, it's good training. But you're implicitely making people think that Python is superior by giving a false positive example.

Answer 10

Naman
just read the comments in this post to understand why this contain 64 line

Answer 11

Costin Onciu
anyway C has limit for variables
even if using array or not

Answer 12

Freddy
awesome idea but how can convert string to number ?! 🤔

Answer 13

Fistefalo
серия чисел, в которых каждое число (число Фибоначчи) является суммой двух предыдущих чисел. Простейшим является ряд 1, 1, 2, 3, 5, 8,

Answer 14

phyton vs c++ is amazing coder its so wow magic

Answer 15

Chris
you forgot one thing ,
that my code can calculate fibonacci series up to 141th number (not 94th as you wrote),
i wrote 30 rows code to break that limit bro😉
#look_carefully #eyes_wide_shut
goodluck

Answer 16

Fistefalo
да, я делаю тот же код, но, к сожалению, в c ++, поскольку вы знаете, что у нас есть ограничение переменной, которое не может хранить верхние значения 18 * (10 ^ 18), поэтому я написал слишком длинный код, чтобы разбить этот предел и вычислить 141-е число фибоначчи с 30 цифр целых чисел :)

Answer 17

OMG
i should learn phython soon.

Answer 18

Fistefalo
я не понимаю, что вы имеете в виду !

Answer 19

You could also write READABLE python programmes
