No , you have to handle it in array

you can code a class or data struct to handle big numbers

    no there must be some way i am sure. Handling with array may create some problems and also too much code to write manually for implementation.

      If the competition allows pre-written code, then there is no problem. Otherwise, addition, subtraction, multiplication and division by a small number are easily implementable within minutes (try to write them one or two times and you'll get the feel of it).

      The is no support for big numbers in the standard library, so the above is the only thing you can do.

      Yes, there is well-known way — as I know most of C++ contestants with high rating have sufficient skills in java and use this language for these rare problems.
