return 0; Function???

Answer 1

You may have to elaborate on your question. What is it that you want to ask?

Answer 2

return 0; can be used in a function, but it is not a function.
In main, since main is a function, return 0 would be simply exiting the programme.

Answer 3

return is simply a statement that transfers control out of the function as a value...
It only signifies the function's state or result...
