No, you can’t.
We can’t define functions inside other functions in C.
With languages like JavaScript, Swift or Python it is pretty common to use nested functions.
C and C++ do not provide this option.
Your next best option is to put the functions you need to perform something in a separate file, and only expose the primary function a client program needs to use, so you can “hide” all the things that does not need to be public.
