was doing an online C++ evaluation test this morning and the last
question required calculating some fairly sizable values (permutations
of lengthy strings). didn't need to print any strings, just calculate
the number of possible permutations, where the final value could be
considerably more than 20! (20 factorial).
even using unsigned long long, some test data exceeded the data
type. wasn't sure if the test wanted me to switch to double float, or
take advantage of a multi-precision library, or what, but am i correct
in that "unsigned long long int" is the best i can get in terms of
maximum value for an integral data type in C++?
