Cgminer only mines with dedicated bitcoin mining hardware plugged into your computer. Neither your CPU nor your GPU can be used to mine bitcoin with.
This is the creator of the software he did this to keep people from ruining their computers, so if you are following an old guide op it is no longer correct as difficulty (how much power needed to mine a block) has gone up. If you just want to play with bitcoin I suggest buying a sidehack usb or if you want to play with altcoins I suggest using this always on pc for staking, if you go with the later look into the altcoin sub topic for more information.
I would second this if your wanting to learn but in a order for a compac. You can learn mining for cheap and it's also fun.
I have a feeling OP is in the dorm or something with "running at my university ". So he might be wanting to mine on "free" electricity. If this is true look at asics that are used and do some ROI math. Also look into sound and heat. Some you honestly would not want to mine with if your in some one room dorm room type space.
I've seen some really nice school housing and some really old housing so I'm not sure what OP has.
