Is it preferable to divide the lengthy software into smaller modules, each of which performs a certain function? These chunks are referred to as functions in C++ programming. Do you have any other comments to make about this?

What exactly is modular programming? Make a list of all the details regarding returning and non-returning functions. Distinguish their prototype, definition, and function call. Extend your explanation with examples from sources other than the text. Also, clarify the concepts of pass by value and pass by reference. in the PROGRAMMING LANGUAGE C (Programming language C)

I know the concept of function and programming well so no need to explain all that. I want to know if I can call a function inside another function or not in c++? If yes, please provide precise and direct code.
