How to erase everything on iphone 5c?

So i need to wipe my phone (Iphone 5c) but i forgot my icloud, and i don't have an itunes thing, and i don't know my restrictions passcode.

I DON't KNOW! I'm SORRY!

Make a new iCloud, back everything up then delete everything as if it was in a factory setting, just in case you're getting a new iPhone and want to restore your phone into a new one you could use iCloud.

Does your iPhone have Find My iPhone enabled? If it does, you WILL need your iCloud account in order to get access. There's no way around it.
