I didn't know what size_t represented until now, and we haven't used it in class yet.

In your case, you are writing it in a function that will not use length afterwards, so it is arguably okay.
Yes I understand that. This code is in a void function right now so I could have added the int return, but I haven't found a reason to need the string length of the user input.
