C and Python Factorial

Question

I write a program to calculate factorial in C and Python programming language with same logic.
But I can't take factorial greater then 20 or 21 in C as it is giving me wrong answer and at factorial of 65 it give me 0 answer.
But in python I was able to take factorial of even 90000 and it was taking so long to calculate factorial of 9000000 i.e., it will give me output.
Why C was not be able to do that

Answer 1

Shail Murtaza as Jan Markus said, any primitive data type of C/C++ can't be used to store value large enough for higher factorials.

But you can always use arrays to tackle this problem 👇

Answer 2

Shail Murtaza factorial of 65 is beyond capacity of unsigned long long int.

Unsigned long long int has capacity of 0 - 18,446,744,073,709,551,615.

Answer 3

C program is working fine.
It is also showing factorial of 65! = 9223372036854775808 (maybe correct 😅)

Happy coding

Answer 4

ツ Priyanshi ツ {PTP} This is not correct
I guess Sololearn's server is better then mine PC so it is not giving 0 output.
Search on Google factorial of 65 or you can use Python

Answer 5

So, What to do?
