Bonjour!

Salut

I don't need to answer this question, Valeuraph made it. I just want to correct your question : "how do you say "hello" in French"

- Bonjour (during the day). - Bonsoir (evening time) - Allô (all day long, but it most likely something you would say while answering the phone) - Salut (all day long, and it's also used to say: Goodbye!)
