They say "Hello". Some of their language (Sinhala) is based on English. The proper way to say hello is, "Ayo Bowan" (pronouced I-U Bow-On with your hands together and a bow). However, regular everyday hello is hello. Hope that answers your question.
Hello is "satsriakal" (sat - shri - akaal) in phonetic Punjabi. Goodbye is "alwida" in phonetic Punjabi.

The language of India is not Indian, it is Hindi. To say hello, you would say "namaste", to be simple. Do take note that India has many states, so the languages they speak may vary. Majority of the East Indian people who live near me are from India's state of Gujarat, so instead of "namaste", I was told to say "Jai Shri Krishna". Well, I used to just say "Good morning/afternoon" to my friend's dad until he told me "To greet, say jai shri Krishna". It has some religious significance to them, so that's what I say from now on.
