What is return really do?
I am really confused about the return a + b + 343, according to this tutorial, seems like it's overwriting the value of funky_math(foo,bar) in the printf section.
So I was wondering if it's true that once I use return in the implementation section, it will automatically replay the value in the printf section?

I'm not quite sure what you mean by "automatically replay the value in the printf section" but the value of the return statement replaces the reference to the function. Instead of
int result = funkymath(numberA,numberB)
, whatever value the return statement returned would replace the call to the function, so in the context of this video, the previous statement would actually mean
int result = numberA+numberB+343 ``` . Sorry if this wasn't what you asked!
Jianhui, the return statement returns a value, in this case an int; to the place where the function was called (in this case inside the printf statement).
