what is the difference

[prasadisri]

What is the difference between,
1.What are you doing
2.How are you doing

T​hey are both incorrect because they lack a finishing punctuation mark. Do you understand the difference between "what" and "how"?

 

[davidddp]

"What are you doing?" The question maker is asking the thing you are currently occupying in.
''How are you doing?'' is a greeting.

Davidddp, it is admirable that you wish to help a fellow learner but there were errors in your post and you did not start your post with "Not a teacher" as you are required to do.

Can you please explain me this question.
WHAT'S UP?

Can you please explain me this question.
WHAT'S UP?

It can be a greeting to which no response is expected.
It can be a greeting to which you reply "Not much. You?" or just "What's up?" back at the person.
It can ALSO be a genuine inquiry about what is happening / what the current situation is.

prasadisri, for the second time, a better title would have been What/How are you doing?.
