keyboard jumbled up

[Ronnie J Dio]

I have an iMac
when I press my space bar a 'c' appears
I think all the keys are jumbled up because now I have restarted my Mac and I can not book on because it says my password is wrong
I am having to type this on my Mac Book Pro

And what exactly purpose does your post serve? Hardware failures happen. If you are still under warranty, let Apple send you a new keyboard. If not - buy a new keyboard.
