Newbie CCENT routing question

When connecting 2 routers, via serial or FE, do the 2 interfaces that are connected via the same cable have to be on the same subnet, will they be able to communicate if they are on a different subnet?
I am trying to setup OSPF with 5 routers in 1 area, and the only way I can setup routing of different subnets on different routers is having the interfaces which connect via the same cable on the same subnet, and then using the other interface on the router to use a different subenet, kind of like daisy chaining, is this the correct way to do it, or is there a way to have 2 interfaces that are connected via the same cable to communicate if they are on different subnets?

    For devices to communicate on seperate subnets, some kind of packet routing needs to occur. So yes, in order for 2 devices to successfully communicate on directly connected links, they need to be on the same subnet.
