How to factory reset my iphone5c?

Ok, this is Really annoying me because no matter what i search every way to reset an iphone is with itunes which i can't do. Trying to reset with itunes says it could not reset and just stops, i need my phone to reset and i can't get into the phone because i forgot my password. I'm really surprised there's not 1 other person in the universe who needs to reset an iphone and have itunes not work

Go to settings then general then scroll down to reset then click reset to factory settings
