Linux doesn't assign drive letters so you won't see C, D or E anywhere. Linux names drives in the form /dev/sda, /dev/sdb, /dev/sdc etc. Partitions are /dev/sda1, /dev/sda2 (ie. 1st and 2nd partitions of the first drive) etc.
What you'll end up with is something like this:
/dev/sda1 - NTFS
/dev/sda2 - EXT4 (or whatever you choose)
/dev/sda3* - SWAP
You don't necessarily need swap if you've got plenty of RAM. Unlike Windows, Linux will use swap only when absolutely necessary. You can just add a 256-512MB partition for good measure if you want. Unless you only have 1GB of RAM you probably won't need more than that
*Possibly /dev/sda5 if the installer decides to make an extended partition (/dev/sda4 which will not show up in the installer) with SWAP on a logical partition inside that. I'm not entirely sure what it will do. If you choose to make a custom partition layout instead of letting the installer do it for you then there will be an option when creating the partition to force it as primary though so do that and you can be certain that it will be /dev/sda3 for simplicity's sake.
