I'm trying to calculate the largest Fib. number less than 100 digits long using the general formula: F(n) = F(n-1)+F(n-2). Need to store it in an array one digit per cell. I checked through the search option and I found one really relevant post. But this post is talking about a large number read from a file... I need to calculate it! I'm trying to gather my thoughts first, and my question is whether to conduct the calculation using digits as strings, just like I would read it from a file??? I am kind of lost how to start. Any hints how to start thinking about it?

Thanks.
