Answer 1

Nandan Kumar Check here. If it possible in Java then why not in C++.

One more thing Ruby automatically understand datatype according to value.

Answer 2

I have once done a factorial function in C++ that can do it.

That's far from a whole Big Integer type obviously.

Answer 3

HonFu Ok

Answer 4

For output there is no data type. And also not only on Sololearn you can get on any IDE.

BTW we can store big numbers in BigInteger in java.

Answer 5

AJ #Level 20 End Game is it possible in c++

Answer 6

AJ #Level 20 End Game unsigned long long allow only upto 2^64-1
unsigned long long allow factorial only upto 20

Answer 7

Nandan Kumar Try and Check. Tell me also.😁

Answer 8

HonFu so there is no in built datatype in C/C++ which is equivalent to Java's biginteger

Answer 9

Nandan Kumar unsigned long long allow. It's equivalent to BigInteger

Answer 10

Nandan Kumar No. Check HonFu code. It's allow upto 100 also. Even upto 1000.

Answer 11

AJ #Level 20 End Game, that only works because I split up the number into an array.

It wouldn't work just with unsigned long long, after 20! it's over.
