multiplication and division of strings

(OP)
hi guys,
could anyone tell me the algorithm for multiplication and division of big strings?
example:12345678901222222758975987689769(string 1)
          646468685567856566575776345567657534(string 2)

thanx.

RE: multiplication and division of strings

There's an ANSI C function strtold() in stdlib.h that converts a string to a long double. Make sure you check the return value and errno after using it to make sure it converted your string successfully. I think this function may be part of the new C99 standard, so if your compiler doesn't provide it, look at strtod().

use linked lists.store the non-zero digits along with their powers in the nodes of a linked list and then perform multiplication and division operations on the lists the same way u do it for polynomials
