Do Nikon D100 lenses fit a D7100?

My wife has a dinosaur Nikon d100 with lenses… Would the lenses fit a D7100?

Every one of them, and just about anything Nikon has ever made in the F mount… Back to the mid 50's.

Nikon lenses are not camera specific. If it will fit a D100, it will fit a D7100.

Yes.

It's the same mount. The lens will fit.
