The dinosaurs have died out but birds may have evolved from them.

Birds are dinosaurs and today everywhere we have birds.
One class of dinosaurs is still alive today: birds.
No The ones alive today are Birds. Whoever answered "no" is completely wrong. The ones alive today are both birds (avian dinosaurs) and usual dinosaurs (non-avian dinosaurs). Whoever answered "No" is completely wrong and is not an answer to that particular question. There are more than around 10 000 species of avian dinosaurs still alive today, and more than around 1300 non-avian dinosaur species are known in the fossil record, it is currently unknown how many of these are still alive, but at least around 100-500 as minimum.

Dinosaurs as most people think of them are completely extinct. However, birds evolved from dinosaurs, and as such, are considered to be a group of dinosaurs. Since birds are still alive today, so are some dinosaurs. No dinosaurs other than birds are alive today, though.
Birds are a group of dinosaur. We know for certain that they are all around us. Therefor, it isn't even a question that dinosaurs are alive today.
Some fish and reptiles were alive when the dinosaurs were and are still alive today. But there are no T-rex's or anything like that anymore.
Well,the dinosaurs your probably thinking of is like T-Rex's and others but there actually is a dinosaur that is still alive...Crocodiles,turtles,some fish and more!
Because they are alive today, birds are dinosaurs. And because of fossils.
The largest animal alive today that is related to dinosaurs would be the saltwater crocodile.
There are many species of animal that were alive at the time of the dinosaurs and are still around today, notable examples being the shark and the tuatara.
