Thanks again for your patient and thoughtful replies, they are a huge help.
I have a few instances where I have function definitions in header files. These are usually functions that are only included when specific things have been defined, #ifdef, etc. I guess it would be better to have the functions definitions in their own object and implement the abstraction in the make file by linking the additional objects under the specified conditions.
So for global variables, you declare those in a header file (as extern), and then include the .h in only one src file? Then you have to re-declare and initialize the var in the same src file where the header is included ? That is so different from Fortran when you have to include global (common) variables in every src file where they are used, and then if you re-declared it, you would get a compiler bonk.
I am still a bit confused about the function prototypes. Lets say we are not using extern "C", can I declare the function prototype (with no code block) in one and only one header file, or do I need to include the header file in every src file that will be using the function. The latter is my current understanding or how things work.

In a well-known book on the C language, there is an example of an efficient method for using a struct member as an argument to a function. (I'm a C noob, but I believe the correct terminology might be: use call-by-reference instead of call-by-value.) The function is printf.
Anyway, here's a... (5 Replies)
