I follow discussions on the Algorithms community on orkut. Came across one question which asked us to implement very big integers in C/C++. We can calculate 12! using integer data type, 20! using long long. Java provides a data type BigInteger which can handle it, Python :) can handle REALLY LARGE VALUES. In C/C++ we can implement this with the help of an integer array where each digit is represented as an element of the array. I have used a class for this purpose.

class large
{
	int no[SIZE];
	public:
		large operator +(large& x);
		large operator *(large& x);
		large (string _no);
		large ();
		void print();
};

I have attached the source code, one can have a look at it. The program could calculate the factorial of 300, which is 616 Characters long :).
