[Solved] how to store a 1000 digit number c++? [duplicate]

Question

You have to use bignum arithmetic which isn’t included in standard C++ library so you either have to write it yourself or use some third party library.

About storing specifically – well it could be stored as an array (or vector) of unsigned ints less than 10000 for example which will represent it’s numbers “digits” by base 10000. There could be a lot of other ways though depending on exact arithmetic implementation.
