hello there, thanks for reading!

I need to prove that the cardinal number of {0,1}^N is the,cardinality of the continuumc.

{0,1)^N is that set {f(x) | f:{0,1} --> N}, i.e., all the functions from the set {0,1} to Natural numbers.

The thing is, I have never learned of sets and cardinal numbers, and the lecturer mentioned briefly what a cardinal number is - so I have no idea how to approach this kind of problem.

Help? Please? Pretty please?

Thanks!
