can power function be used to calulate the power of very large values like pow(200,200).
also can it be used for long long int values … pow(long long int,long long int).
i am getting this error
/sources/tested.cpp: In function 'int main()':
/sources/tested.cpp:16: error: call of overloaded 'pow(long long int&, long long int&)' is ambiguous

If you're looking to do arbitrary precision math, you'll need to get a library for it. Likely, your platform doesn't have data types large enough to do so natively. Check out GNU MP.
