[Haskell-cafe] Learning C after Haskell

Thanks, Minh. So are things like recursion and memory sharing typically out
the window?

Also, I don't see how thinking about type classes will help, without the
benefits of polymorphism.

C is very different from Haskell.
* you'lle have to manage explicitly memory de/allocation.
* c programming is a bit like haskell io monad programming (but
without the functionnal part) :
  you'lle use "=" in place of "<-" and the left hand side can be
reassigned multiple times.
* imperative programming (c is imperative) involve states (a lot !).
  (see how to write the equivalent of mapM print [1..10]);
  imperative programmers use loops, not much recursion

* things you can keep in your mind : the way you organize things
(module, type classes (but there is no polymorphism in c), have
functions and not a huge amount of code lines...), the way you use
self documenting names.

well, not sure it helps, but here you are :)
